Layered Transition Metal Selenophosphites for Visible Light Photoelectrochemical Production of Hydrogen

Sunny Goswami

Global energy use is increasing, posing severe threats to environmental protection and energy sources. Introduction of clean and sustainable energy sources, such as photo electrochemical hydrogen fuel production, is a possible answer. 2D materials, such as transition metal trichalcogenphosphites (MPCh3), are gaining more and more interest for their potential as photocatalysts. Transition metal selenophosphites, such as MnPSe3, FePSe3, and ZnPSe3, have been investigated as photo catalysts for the Hydrogen Evolution Reaction (HER). During photocurrent studies in acidic environments, ZnPSe3 showed the lowest overpotential and the highest responsiveness to light.
