主 题：MoS2 nanosheet ion irradiation electrocatalyst hydrogen evolution reaction sulphur vacancy
摘 要：The inert basal plane of molybdenum disulfide (MoS2) restrains its further hydrogen evolution reaction (HER) *** work attempts ion irradiation to activate inert basal plane of MoS2 nanosheet to improve its electrocatalytic *** results demonstrate the sulphur vacancies generated by ion irradiation on the basal plane of MoS2 mainly boost the efficiency of HER *** moderate fluence of carbon ion irradiation gains the optimum HER performance with an onset potential of 77 mV and Tafel slope of 66 mV/dec.
