A class of metal diboride electrocatalysts synthesized by a molten salt-assisted reaction for the hydrogen evolution reaction†
Abstract
A family of twelve monometallic diborides, containing transition metals from group IVB elements to group VIII elements, and Ni–W bimetallic diborides are synthesized via a molten salt-assisted method. Their trend in activity for the hydrogen evolution reaction is studied, with Ni–W bimetallic diborides acting as the most efficient, nonprecious electrocatalysts.
