Abstract
Thiol-terminated porphyrins are covalently attached to 2D-MoSe<sub>2</sub> edges. The HER activity is enhanced (or suppressed) by the presence (or absence) of hydroxyl groups in the porphyrin. The porphyrin/MoSe<sub>2</sub> hybrid forms a type II heterojunction with improved photoactivity.
