Abstract

Here we report a high performance nanoporous silicon photoelectrode deposited with earth abundant [Mo3S13]2- nanoclusters for hydrogen generation. The earth abundant [Mo3S13]2- nanoclusters with controllable loading can be facilely deposited onto nanoporous Si via drop coating of the monodispersed [Mo3S13]2- suspension followed by drying. The nanoporous Si photoelectrode exhibited a [similar]200 mV lower onset potential for photocurrent by reducing the interface resistance for hydrogen generation. The deposition of [Mo3S13]2- also passivates the nanoporous Si with a more stable photocurrent for hydrogen generation than b-Si in a 20 000 s test.
