Solar hydrogen production achieved with a new class of materials developed in Rennes

(Advanced Science 2021) In the work which has just been published in the prestigious journal “ Advanced Science ”, the Rennes team proposes to use a new family of materials with quite astonishing photoelectric properties to produce solar hydrogen efficiently, at low cost and with a low environmental impact. This proposal is accompanied by several demonstrations of photoelectrodes operating under solar illumination. (...)
