Cover Story: Metal organic nanomaterials are promising constituents in the fabrication of efficient, and low-cost photoelectrodes for solar fuels. In this work, we synthesise a metal organic cluster complex {Ni4O4} and pair it with silicon nanowire (SiNW) electrodes to enhance the reductive photocurrent response for hydrogen generation. We show an enhanced photocurrent response of 60% when compared to bare SiNWs and verify our system as an efficient and stable photocathode for water splitting. View this paper.
