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