A plasma oxidation method is developed to fabricate atomic-scale pores in the basal planes of electrochemically inert TaS2 nanosheets functionalize 2D crystals with high electrocatalysis for hydrogen evolution reaction. Quantitative measurements under-coordinated atoms at edges by aberration-corrected transmission electron microscopy reveal intrinsic correlation between defective atomic sites and electrocatalytic activities .
