Exploitation of the Large-Area Basal Plane of MoS₂ and Preparation of Bifunctional Catalysts through On-Surface Self-Assembly.

ABSTRACT: The development of nonprecious electrochemical catalysts for water splitting is a key step to achieve a sustainable energy supply for the future. Molybdenum disulfide (MoS₂) has been extensively studied as a promising low-cost catalyst for hydrogen evolution reaction (HER), whereas HER is only catalyzed at the edge for pristine MoS₂, leaving a large area of basal plane useless. Herein, on-surface self-assembly is demonstrated to be an effective, facile, and damage-free method to take full advantage of the large ratio surface of MoS₂ for HER by using multiscale simulations. It is found that as supplement of edge sites of MoS₂, on-MoS₂ M(abt)₂ (M = Ni, Co; abt = 2-aminobenzenethiolate) owns high HER activity, and the self-asse
