Expediting hydrogen creation with a non-noble metal cocatalyst under visible light

Halide perovskites have been emerging as promising photocatalytic materials for H2-evolution from water due to their outstanding photoelectric properties. However, the lack of proper surface reactive sites greatly hinders the photocatalytic potential of these fascinating compounds. In this work, Mo2C nanoparticles have been anchored onto methylammonium lead iodide (MAPbI3) as a non-noble-metal cocatalyst to promote H2-evolution reactions.
