Optimized H2-evolving dye-sensitized LaFeO3 photocathodes prepared via the layer-by-layer assembly of dyes and catalysts

Abstract

A molecular dye and a molecular catalyst were loaded onto the surface of a mesoporous LaFeO3 (LFO) film via layer-by-layer assembly relying on the coordination of phosphates and Zr4+. After assembling six layers of the dye and four layers of the catalyst, the (NiP-4 + PQA-6)@LFO photocathode exhibited a significant photocurrent for light-driven H2 generation.
