چکیده
Copper oxide is used as a catalyst or precursor in chemical reactions that involve hydrogen reactant product. Controlled reduction and therefore known kinetics of well-defined Cu-oxides key issue for the activation catalysts well other technological fields such gas sensing. The mechanisms single-phase CuO Cu2O films 5 vol% H2/Ar were investigated by in-situ real time synchrotron-based X-ray diffraction measurements. To this end, incubation time, → Cu phase transformation rates, microstructure strain state evolving Cu, phases studied during reduction. Highly porous scaffolds obtained alternating oxidation steps, which can be envisaged wealth applications catalysis, batteries, water treatment biomedical applications.

Reduction of CuO in H2: in situ time-resolved XRD studies
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 H2 with pure powders and films of CuO was carried out using in situ time-resolved X-ray diffraction (XRD) and surface science techniques. Oxide reduction was observed at atmospheric H2 pressures and elevated temperatures (150–300 8C), b...

This study reports on a Cu-sputtered film on polystyrene (PS) leading to the discoloration/degradation of methylene blue (MB) under low intensity solar simulated irradiation. Direct current magnetron sputtering (DCMS) was used to graft uniform, adhesive Cu/Cu oxides on the polystyrene substrate. The kinetics of Cu-PS mediated MB-discoloration adding H2O2 was observed to take place within 90–120...

Mechanical Properties of Cu2O Thin Films by Nanoindentation
In this study, the structural and nanomechanical properties of Cu₂O thin films are investigated by X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and nanoindentation techniques. The Cu₂O thin films are deposited on the glass substrates with the various growth temperatures of 150, 250 and 350 °C by using radio frequency magnetron sputtering. The XRD re...
