Photoelectrochemical Water Splitting with ITO/WO₃/BiVO₄/CoPi Multishell Nanotubes Enabled by a Vacuum and Plasma Soft-Template Synthesis.

ABSTRACT: A common approach for the photoelectrochemical (PEC) splitting of water relies on the application of WO₃ porous electrodes sensitized with BiVO₄ acting as a visible photoanode semiconductor. In this work, we propose a new architecture of photoelectrodes consisting of supported multishell nanotubes (NTs) fabricated by a soft-template approach. These NTs are formed by a concentric layered structure of indium tin oxide (ITO), WO₃, and BiVO₄, together with a final thin layer of cobalt phosphate (CoPi) co-catalyst. The photoelectrode manufacturing procedure is easily implementable at a large scale and successively combines the thermal evaporation of single crystalline organic nanowires (ONWs), the magnetron sputtering deposition of ITO and WO₃
