Efficient Photocatalysts Made by Uniform Decoration of Cu(2)O Nanoparticles on Si Nanowire Arrays with Low Visible Reflectivity

Highly uniformed decorations of Cu(2)O nanoparticles on the sidewalls of silicon nanowires (SiNWs) with high aspect ratio were prepared through a two-step electroless deposition at room temperature. Morphology evolutions and photocatalytic performance of SiNWs decorated with aggregated and dispersed...

description Highly uniformed decorations of Cu(2)O nanoparticles on the sidewalls of silicon nanowires (SiNWs) with high aspect ratio were prepared through a two-step electroless deposition at room temperature. Morphology evolutions and photocatalytic performance of SiNWs decorated with aggregated and dispersed Cu(2)O nanoparticles were unveiled, and the correlated photodegradation kinetics was identified. In comparison with the conventional direct loadings where the aggregated Cu(2)O/SiNW structures were created, the uniform incorporation of Cu(2)O with SiNWs exhibited more than three and nine times of improved photodegradation efficiency than the aggregated-Cu(2)O/SiNWs and sole SiNWs, respectively. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this article (10.1186/s11671-018-2735-7) contains supplementary material, which is available to authorized users.
