| 英文摘要 | electrocatalytic splitting of water is one of the most efficient technologies for hydrogen production, and two-dimensional (2d) mos2 has been considered as a potential alternative to pt-based catalysts in the hydrogen evolution reaction (her). however, the catalytic activity of 2d mos2 is always contributed from its edge sites, leaving a large number of in-plane domains useless. herein, we for the first time demonstrated that the catalytic activity of in-plane s atoms of mos2 can be triggered via single-atom metal doping in her. in experiments, single pt atom-doped, few-layer mos2 nanosheets (pt-mos2) showed a significantly enhanced her activity compared with pure mos2, originating from the tuned adsorption behavior of h atoms on the in-plane s sites neighboring the doped pt atoms, according to the density functional theory (dft) calculations. furthermore, the her activity of mos2 doped with a number of transition metals was screened by virtue of dft calculations, resulting in a volcano curve along the adsorption free energy of h atoms (delta g(h)degrees), which was further confirmed in experiment by using non-precious metals such as co and ni atoms doping 2d mos2 as the catalysts. |
