Highly uniformed decorations of CuO 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 CuO nanoparticles were unveiled, and the correlated photodegradation kinetics was identified. In comparison with the conventional direct loadings where the aggregated CuO/SiNW structures were created, the uniform incorporation of CuO with SiNWs exhibited more than three and nine times of improved photodegradation efficiency than the aggregated-CuO/SiNWs and sole SiNWs, respectively.
通过室温下的两步化学沉积法，在具有高纵横比的硅纳米线（SiNWs）侧壁上制备了高度均匀的氧化铜纳米颗粒装饰层。揭示了聚集和分散的氧化铜纳米颗粒装饰的硅纳米线的形貌演变和光催化性能，并确定了相关的光降解动力学。与形成聚集的CuO/SiNW结构的传统直接负载方法相比，氧化铜与硅纳米线的均匀结合分别比聚集的CuO/SiNWs和单一的硅纳米线表现出提高了三倍和九倍以上的光降解效率。
