Abstract

We synthesized a CuRh₁Cr₁ DMSC with isolated Rh and Cr single atoms in Cu nanoparticles via a spark ablation in liquid (SAL) method. The isolated Rh and Cr single atoms have different coordination environments and can synergistically drive the catalytic process. The alkaline HER electrocatalytic performance of the CuRh₁Cr₁ DMSC is comparable to that of commercial Pt/C.
