Transition metal dichalcogenides (TMdCs) are excellent electrocatalyst for HER. (I) The simple monolayer structure allows for fundamental reaction mechanism study and (II) the precise control of atomic scale active sites in order to improve catalytic performance.
With this interest, our group substitutionally dope 2D monolayer TMdCs by Chemical vapor deposition and investigate the HER activity of the single atom catalyst (SACs) active centers in the TMdCs.
