Liquid metal-embraced photoactive films for artificial photosynthesis.

ABSTRACT: The practical applications of solar-driven water splitting pivot on significant advances that enable scalable production of robust photoactive films. Here, we propose a proof-of-concept for fabricating robust photoactive films by a particle-implanting technique (PiP) which embeds semiconductor photoabsorbers in the liquid metal. The strong semiconductor/metal interaction enables resulting films efficient collection of photogenerated charges and superior photoactivity. A photoanode of liquid-metal embraced BiVO₄ can stably operate over 120 h and retain ~ 70% of activity when scaled from 1 to 64 cm². Furthermore, a Z-scheme photocatalyst film of liquid-metal embraced BiVO₄ and Rh-doped SrTiO₃ particles can drive overall water splitting under visibl
