Single-step fabrication of 3D hierarchical ZnO/ZnS heterojunction branched nanowires by MOCVD for enhanced photoelectrochemical water splitting

We report a systematic and scalable single-step growth of three-dimensional hierarchical ZnO/ZnS heterojunction branched nanowires (3D ZnO/ZnS h-b-NWs) on a Si substrate using MOCVD for the first time and their application as photoanodes for photoelectrochemical water splitting (PEC-WS). Vertically well-aligned main trunk ZnO nanowires (M...More
