Abstract

A new MoS₂ protected n⁺p-junction Si photocathode for the renewable H2 evolution is presented here. MoS₂ acts as both a protective and an electrocatalytic layer, allowing H₂ evolution at 0 V vs. RHE for more than 5 days. Using a MoSx surface layer decreases the overpotential for H₂ evolution by 200 mV.
