2003年8月6日 · Time-resolved X-ray diffraction, X-ray absorption fine structure, and first-principles density functional calculations were used to investigate the reaction of CuO and Cu 2 O with H 2 in detail. The mechanism for the reduction of CuO is complex, involving an induction period and the embedding of H into the bulk of the oxide.

2022年6月30日 · Single phase CuO and Cu 2O thin films are obtained by controlled oxidation of Cu layers of 50–300 nm thickness. CuO and Cu 2O thin films are reduced in H2 atmosphere into nanoporous Cu. Reduction kinetics is monitored by in-situ real time XRD analysis. Grain sizes and strain of CuO, Cu2 O and/or Cu during reduction have been resolved.

Abstract: Time-resolved X-ray diffraction, X-ray absorption fine structure, and first-principles density functional calculations were used to investigate the reaction of CuO and Cu2O with H2 in detail. The mechanism for the reduction of CuO is complex, involving an induction period and the embedding of H into the bulk of the oxide.

CuO is used as a catalyst or catalyst precursor in many chemical reactions that involve hydrogen as a reactant or product. A systematic study of the reaction of H 2 with pure powders and films of CuO was carried out using in situ time-resolved X-ray …

2025年3月19日 · Overall, CuO+H 2 O nanofluid improves the tower characteristic, with varying effects depending on the concentration levels. In conclusion, the experimental results highlight the positive impact of the packing density and CuO+H 2 O on the CT performance, with higher concentrations of nanofluid and denser packing leading to improved cooling ...
