Abstract

We report a H<sub>2</sub> evolving hybrid photocathode based on Sb<sub>2</sub>Se<sub>3</sub> and a precious metal free molecular catalyst. Through the use of a high surface area TiO<sub>2</sub> scaffold, we successfully increased the Ni molecular catalyst loading from 7.08 ± 0.43 to 45.76 ± 0.81 nmol cm<sup>-2</sup>, achieving photocurrents of 1.3 mA cm<sup>-2</sup> at 0 V <i>vs.</i> RHE, which is 81-fold higher than the device without the TiO<sub>2</sub> mesoporous layer.
