Mo2C quantum dot embedded chitosan-derived nitrogen-doped carbon for efficient hydrogen evolution in a broad pH range†
Abstract
A Mo2C quantum dot (averagely 2 nm) embedded N-doped graphitic carbon layer (Mo2C QD/NGCL) is prepared through a simple, green and scalable solid-state reaction. This material exhibits remarkable hydrogen evolution reaction (HER) catalytic activity and durability at all pH values owing to the synergistic effect between Mo2C QDs and NGCLs.
