a Unit cell structures of 2H-MoS2 and 1T-MoS2. HRTEM images for b 2H-MoS2 and c 1T-MoS2. d Schematic representation of the oxidation process and partial restoration of the MoS2 edges after several voltammetric cycles. e HER polarization curves of 1T and 2H MoS2 before and after edge oxidation. Dashed lines indicate the iR-corrected polarization curves
