N2O decomposition over CuO/CeO2 catalyst: New insights into reaction mechanism and inhibiting action of H2O and NO by operando techniques

In this work, a combination of ex situ (STEM-EELS, STEM-EDX, H2-TPR and XPS), in situ (CO-DRIFTS) and operando (DR UV?vis and DRIFTS) approaches was used to probe the active sites and determine the mechanism of N2O decomposition over highly active 4?wt.% Cu/CeO2 catalyst. In addition, reaction pathways of catalyst deactivation in the presence of NO and H2O were identified. The results of operando DR UV?vis spectroscopic tests suggest that [Cu?O?Cu]2+ sites play a crucial role in catalytic N2O decomposition pathway. Due to exposure of {1?0?0} and {1?1?0} high-energy surface planes, nanorod-shaped CeO2 support simultaneously exhibits enhancement of CuO/CeO2 redox properties through the presence of Ce3+/Ce4+ redox pair. Its dominant role of binuclear Cu+ site regeneration through the recombination and desorption of molecular oxygen is accompanied by its minor active participation in direct N2O decomposition. NO and H2O have completely different inhibiting action on the N2O decomposition reaction. Water molecules strongly and dissociatively bind to oxygen vacancy sites of CeO2 and block further oxygen transfer as well as regeneration of catalyst active sites. On the other hand, the effect of NO is expressed through competitive oxidation to NO2, which consumes labile oxygen from CeO2 and decelerates [Cu+ Cu+] active site regeneration.

Toward Long-Term Stable and Highly Efficient Perovskite Solar Cells via Effective Charge Transporting Materials

Perovskite solar cells (PSCs) have advanced quickly with their power conversion efficiency approaching the record of silicon solar cells. However, there is still a big challenge to obtain both high efficiency and long-term stability for future commercialization of PSCs. The major instability issue is associated with the decomposition or phase transition of perovskite materials that are believed to be intrinsically unstable under outdoor working conditions. Herein, the authors review the approaches that marked important progress in developing new functional electron/hole transporting materials that enabled highly efficient and stable PSCs. The findings that accelerate charge diffusion and that suppress the irrevocable loss of ions diffusing out of perovskite materials and other diffusion processes are highlighted. In addition, derivative interface engineering methods to control the diffusion process of charges/ions/molecules are also reviewed. Finally, the authors propose key research issues in charge transporting materials and interface engineering with regard to the important diffusion processes that will be one of the keys to realize highly efficient and long-term stable PSCs.

High-Performance P-Type Copper(I) Thiocyanate Thin Film Transistors Processed from Solution at Low Temperature

Semiconducting copper(I) thiocyanate (CuSCN) is actively studied for electronic and optoelectronic applications. Although various kinds of CuSCN-based transistors are reported, these devices suffer from low charge carrier mobility of about 0.01?0.1 cm2 V?1 s?1. Here, ion gel electrolyte consisting of network polymer and ionic liquid is used as a high capacitance gate insulator to achieve high performance CuSCN-based electrolyte-gated transistors (CuSCN-EGTs) with low operation voltage below 1 V. 30 nm thick CuSCN semiconductor film can be formed by a simple solution process with a low processing temperature (?100 C) that is directly applicable to flexible plastic substrates. By doping copper iodide to the CuSCN semiconductor, device performance including drain current and charge carrier mobility of the CuSCN EGT can be improved significantly. The measured charge carrier mobility of ?0.3 cm2 V?1 s?1 is the highest among the reported CuSCN transistors using various gate insulators. These CuSCN-EGTs also display good operation stability under continuous quasistatic external gate voltage sweeps. Such superior electrical performance and versatile processability of ion gel?gated CuSCN transistors make them suitable for use in complimentary circuits and large-area flexible electronics.

Understanding of perovskite crystal growth and film formation in scalable deposition processes

Hybrid organic-inorganic perovskite photovoltaics (PSCs) have attracted significant attention during the past decade. Despite the stellar rise of laboratory-scale PSC devices, which have reached a certified efficiency over 25% to date, there is still a large efficiency gap when transiting from small-area devices to large-area solar modules. Efficiency losses would inevitably arise from the great challenges of homogeneous coating of large-area high quality perovskite films. To address this problem, we provide an in-depth understanding of the perovskite nucleation and crystal growth kinetics, including the LaMer and Ostwald ripening models, which advises us that fast nucleation and slow crystallization are essential factors in forming high-quality perovskite films. Based on these cognitions, a variety of thin film engineering approaches will be introduced, including the anti-solvent, gas-assisted and solvent annealing treatments, Lewis acid-base adduct incorporation, etc., which are able to regulate the nucleation and crystallization steps. Upscaling the photovoltaic devices is the following step. We summarize the currently developed scalable deposition technologies, including spray coating, slot-die coating, doctor blading, inkjet printing and vapour-assisted deposition. These are more appealing approaches for scalable fabrication of perovskite films than the spin coating method, in terms of lower material/solution waste, more homogeneous thin film coating over a large area, and better morphological control of the film. The working principles of these techniques will be provided, which direct us that the physical properties of the precursor solutions and surface characteristics/temperature of the substrate are both dominating factors influencing the film morphology. Optimization of the perovskite crystallization and film formation process will be subsequently summarized from these aspects. Additionally, we also highlight the significance of perovskite stability, as it is the last puzzle to realize the practical applications of PSCs. Recent efforts towards improving the stability of PSC devices to environmental factors are discussed in this part. In general, this review, comprising the mechanistic analysis of perovskite film formation, thin film engineering, scalable deposition technologies and device stability, provides a comprehensive overview of the current challenges and opportunities in the field of PSCs, aiming to promote the future development of cost-effective up-scale fabrication of highly efficient and ultra-stable PSCs for practical applications.

Construction of 1-2D CuI(or CuII) metal-organic architectures with metal thiocyanates and bipyridyl spacers: Syntheses, structures, and thermal properties

Three new coordination polymers based on IB metal thiocyanates, [CuII(NCS)2(DMSO)4(meso-dpb)]n (1), [Cu2II (NCS)4 (bpp)4]n (2), [CuI(NCS)(pia)]n (3) (dpb = 2,3-di(4-pyridyl)-2,3-butanediol, bpp = 1,3-bis(4-pyridyl)propane, pia = N,N?-(1,2-phenylene)diisonicotinamide), have been synthesized by the pre-assembly method and characterized by X-ray crystallography. In 1, CuII cations are bridged by meso-dpb ligands to form a one-dimensional (1D) linear chain. Compound 2 consists of 2D undulated layers of (4, 4) topology that show twofold parallel interpenetration. In the case of 3, the MI center adopts tetrahedral coordination geometry and the 2D networks are formed by organic ligand with “folding ruler-shaped” NCS–M chains. The thermal properties of 1-3 were also investigated.

Synthesis, structures, luminescence and terahertz time-domain spectroscopy of nine Cu(I) complexes with P^P ligands and 1,10-phenanthroline derivatives

Nine new copper(I) complexes bearing 1,3-bis(diphenylphosphino)propane (dppp) and 4,7-diphenyl-1,10-phenanthroline (batho) or 2,9-dimethyl-1,10-phenanthroline (neo) have been synthesized and characterized. Single crystal X-ray diffraction analysis reveals that complexes 1?4 and 6?9 are mononuclear with similar structures, while complex 5 is a binuclear structure. They display absorption around 280 nm and 410 nm, and the intensive emission in the range of 520?620 nm in the solid state occurring with lifetimes on the mus timescale indicates phosphorescence. Our TD-DFT calculations show that emission from the lowest excited triplet state T1 is of 3MLCT nature. This study manifests that these simple and long-lifetime Cu(I) systems may exhibit a similar, but more complex excited state behavior than the systems previously appreciated.
