Single Pt atomic sites anchored on 1T′ phase MoS2 nanosheets towards efficient hydrogen evolution

Although single-atom catalysts (SACs) are emerging as potential contenders for heterogeneous catalysis, interactions between metal single-atom active sites and support matrix remain uncertain. In a recent issue of Nature, Zhang and coworkers revealed the phase-dependent growth of single atom Pt on 1 T′ phase MoS2 for efficient hydrogen evolution. However, some analyses of the nature of catalyst structure and properties are still lacking, and the relevant large-scale commercial application is still difficult.
