This patent describes a method for improving product yield in an anionic metalloporphyrin-based artificial photosynthesis system for hydrogen generation. The method consists of: forming an aqueous solution comprising an electron donor, methylviologen, and a metalloporphyrin or metallochlo-irradiating the aqueous solution with light in the presence of a catalyst.
