dc.description.abstract | Introducing sulfur vacancies (S-V) in monolayer molybdenum disulfide (MoS2) is a well-known approach to activate the inert basal planes for efficient hydrogen evolution reaction (HER). However, higher S-V induction accelerates the disruption of the crystal structure. We report an efficient method for improving catalytic activity and durability via covalent melamine (MEL) functionalization at S-V sites in the basal plane of transition metal dichalcogenide (TMD) monolayers. Functionalized 2H-MoS2 requires only an overpotential of 160 mV at 100 mAcm(-2) in acidic medium with chronoamperometric durability of more than 14 h at 30 mAcm(-2). Our theoretical results reveal that chemical functionalization creates novel HER active sites, where catalytic activity of the MEL-MoS2 catalyst arises from the interplay of the ring N sites of the MEL and the S atoms on the 2H-MoS2 surface. These findings of chemically coupled organic molecule-TMD system will pave new avenues for development of superior HER catalysts. (C) 2022 Elsevier Ltd. All rights reserved. | - |
