TiO2/Cu2O/CuO multi-nanolayers highly sensitive toward volatile organic compounds (VOCs) and H2 have been grown in various thicknesses by a cost-effective reproducible combined spray–sputtering–annealing approach. The ultrathin TiO2 films were deposited spray pyrolysis on top of sputtered–annealed Cu2O/CuO nanolayers to enhance their gas sensing performance improve protection against corrosion ...

Mixing TiO2 with Mo2C has recently been proposed to improve the photocatalytic conversion of CO2 methanol under visible light irradiation, although further efforts are still needed enhance process performance. In this context, use p-type semiconductors (i.e., Cu2O) in co-doping strategies can not only redistribution electric charges due its narrowing bandgap, but also selectivity reaction towar...

In the present work, we introduce a facile and reliable approach to decorate TiO2 nanotubes homogenously with wellseparated copper oxide nanoparticles. For this, we use a palladium-containing titanium alloy (commercial Ti 0.2 atom% Pd) and grow anodic, self-organized oxide nanotubes. Palladium is embedded in the tube wall during growth and acts as activator for a subsequent electroless copper-n...

A series of CuO-Cu2O/TiO2 nanocomposite samples were prepared by the sol-gel method. Before applying the sol-gel method, the Cu(OH)2 nanostructure on Cu powders were formed by in-situ solution treatment. The samples were characterized through some techniques and the photocatalytic performance of CuO-Cu2O/TiO2 nanocomposites for gas-phase 2-propanol photo-oxidation under UV and sunlight type ill...

New Cu2O@TiO2 core-shell microspheres were successfully prepared for the first time in this paper. The XRD, N2 adsorption-desorption, SEM, TEM, EDX and XPS characterizations utilized to investigate physical chemical properties. liquid phase oxidation of naphthalene was also carried out test their catalytic performance. characterization results indicating that Cu2O firstly formed by hydrothermal...

This study focused on the copper (I) oxide (Cu2O) that serves as an absorber layer, owing to its excellent optical properties, while titanium dioxide (TiO2) is a well-known material has superior properties in solar cell development. In this work, TiO2 nanorods layer was synthesised fluorine-doped tin (FTO) glass substrate by facile hydrothermal method followed stacking Cu2O using low-cost elect...

A novel and facile strategy has been successfully developed to synthesize uniform gold@titanium dioxide octahedral nanocages (Au@TiO2), which have a well-defined double-shelled structure with Au as the internal shell and TiO2 as the external shell. The unique Au@TiO2 double-shelled octahedral nanocages were elaborately fabricated by a Cu2O-templated strategy combining with spatially confined ga...
