Non-noble bimetallic NiMoO4 nanosheets integrated Si photoanodes for highly efficient and stable solar water splitting

Non-noble bimetallic NiMoO4 nanosheet/TiO2 film/Si core-shell nanowire arrays were designed and synthesized by a combined process of hydrothermal, chemical etching, and atomic layer deposition. As photoanodes of photoelectrochemical cells, the hierarchical structure not only lowered the onset potential and enhanced photocurrent density, but also improved the long-term operation stability.296
