Boosting the Productivity of Electrochemical CO₂ Reduction to Multi-Carbon Products by Enhancing CO₂ Diffusion through a Porous Organic Cage was written by Chen, Chunjun;Yan, Xupeng;Wu, Yahui;Liu, Shoujie;Zhang, Xiudong;Sun, Xiaofu;Zhu, Qinggong;Wu, Haihong;Han, Buxing.

Electroreduction of CO₂ into valuable fuels and feedstocks offers a promising way for CO₂ utilization. However, the commercialization is limited by the low productivity. Here, we report a strategy to enhance the productivity of CO₂ electroreduction by improving diffusion of CO₂ to the surface of catalysts using porous organic cages (POCs) as an additive. It was noted that the Faradaic efficiency (FE) of C2+ products could reach 76.1 % with a c.d. of 1.7 A cm^-2 when Cu-nanorod(nr)/CC3 (one of the POCs) was used, which were much higher than that using Cu-nr. Detailed studies demonstrated that the hydrophobic pores of CC3 can adsorb a large amount of CO₂ for the reaction, and the diffusion of CO₂ in the CC3 to the nanocatalyst surface is easier than that in the liquid electrolyte. Thus, more CO₂ mols. make contact with the nanocatalysts in the presence of CC3, enhancing CO₂ reduction and inhibiting generation of H₂. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2HPLC of Formula: 20427-59-2).

Abstract: This paper reports the generation of a type of carbon-based catalyst co-doped by Cu, S and N as efficient ORR catalysts in alk. media. The electrocatalyst performs superior activity for ORR with onset and a half-wave potential (E_1/2) of 0.945 V and 0.847 V, resp., in 0.1 M KOH, comparable with Pt/C (0.955 V and 0.88 V).

A Green Approach for High Oxidation Resistance, Flexible Transparent Conductive Films Based on Reduced Graphene Oxide and Copper Nanowires was written by Lin, Ya-Ting;Huang, Da-Wei;Huang, Pin-Feng;Chang, Li-Chun;Lai, Yi-Ting;Tai, Nyan-Hwa. And the article was included in Nanoscale Research Letters in 2022.Category: copper-catalyst This article mentions the following:

Copper nanowires (CuNWs)-based thin film is one of the potential alternatives to tin-doped indium oxide (ITO) in terms of transparent conductive films (TCFs). However, the severe problem of atm. oxidation restricts their practical applications. In this work, we develop a simple approach to fabricate highly stable TCFs through the dip-coating method using reduced graphene oxide (rGO) and CuNWs as the primary materials. Compared with previous works using toxic reduction agents, herein, the CuNWs are synthesized via a green aqueous process using glucose and lactic acid as the reductants, and rGO is prepared through the modified Hummers ‘ method followed by a hydrogen-annealing process to form hydrogen-annealing-reduced graphene oxide (h-rGO). In the rGO/CuNWs films, the dip-coated graphene oxide layer can increase the adhesion of the CuNWs on the substrate, and the fabricated h-rGO/CuNWs can exhibit high atm. oxidation resistance and excellent flexibility. The sheet resistance of the h-rGO/CuNWs film only increased from 25.1 to 42.2 Ω/sq after exposure to ambient atm. for 30 days and remained almost unchanged after the dynamic bending test for 2500 cycles at a constant radius of 5.3 mm. The h-rGO/CuNWs TCF can be not only fabricated via a route with a superior inexpensive and safe method but also possessed competitive optoelectronic properties with high elec. stability and flexibility, demonstrating great opportunities for future optoelectronic applications. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Category: copper-catalyst).

The sluggish charge transfer and poor intrinsic activity are the bottlenecks that hamper the further development of electrocatalysts for hydrogen evolution. A novel core-shell heterostructure of Cu₃P@Ni is fabricated, which is composed of Cu₃P nanorods covered by metallic Ni. The as-prepared Cu₃P@Ni exhibits a durable and superior activity toward hydrogen evolution, with an overpotential of 42 mV to deliver 10 mA·cm^-2 and a Tafel slope of 41 mV·dec^-1.

A direct ammonia microfluidic fuel cell is a potential portable carbon-free clean energy device. In this work, a NiCu-based core-shell 3D electrode is obtained by electrodeposition and surface electrochem. reconstruction on the nickel foam substrate. The phys. characterization results confirm the core-shell structure with NiCu as the core and Cu(OH)₂ and NiOOH as the shell. In the 3D electrode, the metal core continuously transfers charge to the surface to transform into active species (NiCu hydroxides), thus accelerating the slow ammonia oxidation reaction kinetics. Furthermore, the 3D porous structure is conducive to the rapid diffusion and transport of ions, which effectively improves the fuel depletion boundary layer problem. Consequently, electrochem. tests indicate that the NiCu@NiCuOOH-NF electrode show excellent ammonia oxidation reaction activity and good stability, reaching a maximum c.d. of 90 mA cm^-2 at the potential of 0.7 V vs. SCE (SCE). When 2 M NaOH + 3 M NH₄Cl is adopted as fuel for the DAMFC, an open circuit voltage of 0.72 V and a peak power d. of 17.1 mW cm^-2 can be obtained, while the limiting c.d. is as high as 102 mA cm^-2.

Novel layered triple hydroxide sphere CO₂ adsorbent supported copper nanocluster catalyst for efficient methanol synthesis via CO₂ hydrogenation was written by Li, Jian;Du, Tao;Li, Yingnan;Jia, He;Wang, Yisong;Song, Yanli;Fang, Xin. And the article was included in Journal of Catalysis in 2022.Synthetic Route of CuH2O2 This article mentions the following:

Copper-based catalysts are playing important roles in CO₂ hydrogenation to methanol. Active copper provides sites for H₂ dissociation, whereas CO₂ adsorption and activation cannot be ignored either. Accordingly, novel Cu/LTH catalysts with copper nanoclusters supported on layered triple hydroxide (LTH) sphere CO₂ adsorbent were developed to improve microstructures and CO₂ adsorption capabilities simultaneously. The results show increasements in copper content enlarge crystallite sizes yet reduce surface areas and pore volumes All Cu/LTH catalysts consist of uniformly dispersed copper nanoclusters on external surfaces of LTH. Catalytic tests reveal remarkable properties of Cu/LTH catalysts compared with conventional catalysts. Further mechanism analyses demonstrate LTH can boost CO₂ adsorption capability at reaction conditions. Due to metal-support interactions, copper species in Cu₃/LTH are more easily reduced mainly in the form of Cu⁺, benefiting directional CO₂ conversion to methanol. Thus, it is feasible and efficient to ameliorate catalyst by incorporating adsorbent for enhanced CO₂ adsorption process.
