我们报道了一种基于Sb2Se3和无贵金属分子催化剂的析氢杂化光电阴极。通过使用高表面积TiO2支架,我们成功地将Ni分子催化剂的负载从7.08±0.43增加到45.76±0.81 nmol cm - 2,在0 V相对于RHE下实现了1.3 mA cm - 2的光电流,比没有TiO2介孔层的器件高81倍。
We report a H2 evolving hybrid photocathode based on Sb2Se3 and a precious metal free molecular catalyst. Through the use of a high surface area TiO2 scaffold, we successfully increased the Ni molecular catalyst loading from 7.08 ± 0.43 to 45.76 ± 0.81 nmol cm−2, achieving photocurrents of 1.3 mA cm−2 at 0 V vs. RHE, which is 81-fold higher than the device without the TiO2 mesoporous layer.
