Photoluminescence, photocatalytic and antibacterial activities of CeO2·CuO·ZnO nanocomposite fabricated by co-precipitation method

Synthesis, characterization, and comparison of antibacterial effects and elucidating the mechanism of ZnO, CuO and CuZnO nanoparticles supported on mesoporous silica SBA-3

“…Two strategies can be adopted to solve these problems. For improving the utilization of visible light by ZnO NPs, 15,16 the recombination of charge carriers of ZnO could be reduced by combining the photocatalysts with CuO. Furthermore, a synergistic antimicrobial effect could be built between ZnO and CuO, as CuO act as an antibacterial agent itself among bimetal oxide system.…”

Synthesizing CuO/CeO2/ZnO Ternary Nano-Photocatalyst with Highly Effective Utilization of Photo-Excited Carriers under Sunlight

“…In this work, we explore whether CuO, CeO 2 co-coupled ZnO, can analogously exhibit improved photocatalytic efficiency as a ternary hetero-structured photocatalyst system. Notably, despite some work reported on CuO/ZnO and CeO 2 /ZnO photocatalysts [ 12 , 14 ], however, the inherent relations between the photocatalytic properties of CuO/CeO 2 /ZnO and each component remain unclear [ 17 , 18 ].…”

Single step fabrication of CuO–MnO–2TiO2 composite thin films with improved photoelectrochemical response

“…6 Several semiconducting nanostructured materials such as perovskite structured organometallic compounds, metal oxides, dye sensitized solar cells, metal composites and solid solutions and polymer-based materials have been tested for this purpose. 7 Multi-metal oxide nanocomposite materials such as CuO-Al 2 O 3 -TiO 2 , 8 CeO 2 -CuO-ZnO, 9 CeO-ZnO-ZnAl 2 O 3 , 10 ZnO-TiO 2 -SnO 2 11 have drawn intensive attention in recent times. The properties which arise from their combination make the materials potentially important and are not necessarily observed in the single individual components.…”
