Facile preparation of highly active and stable CuO-CeO2 catalysts for low-temperature CO oxidation via a direct solvothermal method

CuO-CeO2 catalysts with different CuO contents prepared via a direct solvothermal method with superior activity as well as excellent water vapor resistance and good stability have been successfully developed for the catalytic oxidation of CO at low temperatures. The catalyst with a Cu/Ce ratio of 2 : 8 (mol/mol) delivers a high CO conversion of 90% at 86 degrees C, and particularly, is stable for at least 50 h even in the presence of water vapor without deactivation. By extensive characterization including ICP-AES, XRD, N-2 adsorption measurement, Raman, XPS, H-2-TPR, CO-TPD, and in situ DRIFTs, it was found that the presence of abundant oxygen vacancies and strong interaction between CuO and CeO2 are responsible for the excellent catalytic performance of the CuO-CeO2 catalysts for low-temperature CO oxidation.

Iron-doped cuprous oxides toward accelerated nonradical oxidation: Doping induced controlled facet transformation and optimized electronic structure

In this study, transition metal-doped and morphology controlled cuprous oxides were synthesized through a facile route and evaluated for bisphenol A (BPA, a model endocrine-disrupting compound) degradation with peroxymonosulfate (PMS). Fe-doped Cu2O exhibited an ultrahigh efficiency for PMS activation and catalytic degradation of BPA. Experimental and computational outcomes illustrate that iron-doping effectively regulated the exposed termination of the oxides and electronic structure of the surrounding copper atoms. Selective radical screening and electron paramagnetic resonance (EPR) spectra witnessed the presence of trace-level free radicals (SO4 center dot-, (OH)-O-center dot and O-2(center dot)-), whereas BPA was primarily oxidized via a nonradical pathway. A surface-confined intermediate (PMS@Fe-Cu2O) was formed via intimate outer-sphere interactions, which exhibited a high oxidizing capacity toward organic substrate via an electron-transfer regime. This study developed atomically engineered cuprous catalysts and provided new mechanistic insights into nonradical oxidation.

Particle-Scale Reduction Analysis of CuFeMnO4 with Hydrogen for Chemical Looping Combustion

In this work, CuFeMnO4 (copper iron manganese oxide) oxygen carrier was characterized using differential scanning calorimetry/thermogravimetric analysis (TGA), in situ X-ray diffraction, and scanning electron microscopy-energy dispersive X-ray spectroscopy (EDS) to gain a clear elucidation of the chemical looping combustion reactions with H-2 which is a component of synthesis gas. A reaction model which best described the experimental TGA reaction data was selected from the analysis. Intrinsic rate of reaction parameters obtained from the study could be used for designing a reactor for scale-up. A model with combined contributions from nucleation and growth model and dimensional phase boundary model was found to exhibit the best correlation with the experimental data. The analysis provided validation of intrinsic reaction rates and other rate parameters.

Novel 3-(3-(aryl)prop-2-yn-1-yl)-5,5-diphenylimidazolidine-2,4-diones were synthesized through the reaction of 5,5-diphenyl-3-(prop-2-yn-1-yl)imidazolidine-2,4-dione and aryl iodides in the presence of a palladium-copper catalytic in CH3CN at room temperature. All prepared compounds were examined against the two bacterial strains, Micrococcus luteus and Pseudomonas aeruginosa and subjected by molecular docking studies. The in silico study carried out to predict the conformation of the examined compounds recommended that these compounds could bind noticeably to key the residues at the active site of dihydropteroate synthase.

Investigation on nanostructured Cu-based electrocatalysts for improvising water splitting: a review

The effective use of earth-abundant electrocatalyst copper in the splitting of water as nanostructures with different combinations is central in replacing noble metals for the industrialization of hydrogen generation. Carbonaceous fuels, being front-line suppliers of energy, adversely affect the environment with greenhouse gas emission. Considering the electrocatalytic way of splitting water, it is one of the finest ways for producing pure hydrogen with a fast rate with no other undesired by-products; hence, researchers across the world have focused maximum attention to make them commercially applicable. To replace the noble metals, transition metal-based catalysts are promising. In this review, we have chosen to highlight solely the importance of Cu-based nanostructures as effective electrocatalysts for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). Moreover, various synthetic approaches with Cu nanostructures such as mono-, bi-, and tri-metallic catalysts as oxides, hydroxides, sulfides, selenides, tellurides, and phosphides were studied for OER and HER in different pH conditions. Hence, this review gives a brief understanding of Cu-based nanostructures in electrocatalytic water splitting and based on this, it can be applied with other advancements in catalysts development for viable hydrogen generation with electrocatalytic water splitting.

Efficient base-free oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid over copper-doped manganese oxide nanorods with tert-butanol as solvent

2,5-Furandicarboxylic acid (FDCA) is an important and renewable building block and can serve as an alternative to terephthalic acid in the production of bio-based degradable plastic. In this study, Cu-doped MnO2 nanorods were prepared by a facile hydrothermal redox method and employed as catalysts for the selective oxidation of 5-hydroxymethylfurfural (HMF) to FDCA using tert-butyl hydroperoxide (TBHP) as an oxidant. The catalysts were characterized using X-ray diffraction analysis, Fourier transform infrared spectroscopy, thermogravimetric analysis, and transmission electron microscopy. The effects of oxidants, solvents, and reaction conditions on the oxidation of HMF were investigated, and a reaction mechanism was proposed. Experimental results demonstrated that 99.4% conversion of HMF and 96.3% selectivity of FDCA were obtained under suitable conditions, and tert-butanol was the most suitable solvent when TBHP was used as an oxidant. More importantly, the Cu-doped MnO2 catalyst can maintain durable catalytic activity after being recycled for more than ten times.

Synergistic effect of catalyst and plasma on CO2 decomposition in a dielectric barrier discharge plasma reactor

Plasma has been widely used in wastewater treatment, material modification and biomedicine due to its unique properties. In this work, a coaxial cylindrical dielectric barrier discharge (DBD) reactor was set up to investigate the effects of electrode materials and catalyst combined with DBD plasma on CO2 decomposition under room temperature and atmosphere pressure. The materials of inner electrode and outer electrode were investigated without catalysts packed in the reactor. It was found that the aluminum rod as inner electrode performed better than copper rod and stainless steel rod due to the moderate thermal conductivity and electrical conductivity of aluminum rod. Nevertheless, copper foil worked better as external electrode material since its higher electrical conductivity facilitated generation of high energy electrons by the high voltage between electrodes. After perovskite-type catalyst was introduced in the reactor, CO2 conversion increased, which was attributed to the synergistic effect of perovskite combined with plasma discharge. Perovskite-type catalysts could modulate the capacitance of the reactor to make plasma discharge more uniform and increased CO2 conversion, while plasma discharge provided high energy electrons that activated oxides sites and basic sites of perovskite-type catalysts. The maximum CO2 conversion was 23 % and maximum energy efficiency was 2.1 % when MgTiO3 was packed in the reactor.

Copper molybdate nanoparticles for electrochemical water splitting application

Two different phases of copper molybdate nanoparticles such as Cu3Mo2O9 and Cu6Mo5O18 were synthesized through schematic hydrothermal treatment. The obtained product morphology was explored by using surfactants like sodium lauryl sulfate (SDS) and polyvinylpyrrolidone (PVP). The structural, optical, vibrational and morphological properties were confirmed employing standard characterization techniques. Rectangular nanoflakes of the obtained product were confirmed by employing Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies. Selected area electron diffraction (SAED) pattern confirms obtained product crystalline nature. The better morphology controlled sample gives higher 227 mA/g current density at 10 mV/s and small 184 V overpotential. Long duration stability over 16 h was exhibited by Cu6Mo5O18 electrode. Hence, Cu6Mo5O18 electrode shows better electrochemical activity with stunning low overpotential. It would be suggested that PVP surfactant is quite optimum to produce efficient Cu6Mo5O18 catalysts for electrochemical water splitting applications. (c) 2020 Hydrogen Energy Publications LLC.

An industrial perspective on catalysts for low-temperature CO2 electrolysis

This Perspective describes the key advances in nanocatalysts that have led to the impressive electrochemical conversion of CO2 to useful products and provides benchmarks that others can use to compare their results. Electrochemical conversion of CO2 to useful products at temperatures below 100 degrees C is nearing the commercial scale. Pilot units for CO2 conversion to CO are already being tested. Units to convert CO2 to formic acid are projected to reach pilot scale in the next year. Further, several investigators are starting to observe industrially relevant rates of the electrochemical conversion of CO2 to ethanol and ethylene, with the hydrogen needed coming from water. In each case, Faradaic efficiencies of 80% or more and current densities above 200 mA cm(-2) can be reproducibly achieved. Here we describe the key advances in nanocatalysts that lead to the impressive performance, indicate where additional work is needed and provide benchmarks that others can use to compare their results.
