title: Atomic-Sized Pores Enhanced Electrocatalysis of TaS2Nanosheets for Hydrogen Evolution.
abstract: A plasma oxidation method is developed to fabricate atomic-scale pores in the basal planes of electrochemically inert TaS2nanosheets 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 TaS2.
