Abstract

For photoelectrochemical NADH regeneration, an electrode-supported “lipid bilayer membrane” photocathode based on a p-Si semiconductor, an electron transport mediator (OBV²⁺), and a [Rh(Cp*)(bpy)Cl]⁺ catalyst was constructed by self-assembly. Mechanistic study shows that OBV²⁺ can enhance the charge transfer between the semiconductor and catalyst, leading to a significant improvement of the NADH photo-regeneration rate.
