| Abstract: |
| The research of Metal-Hydrogen system is important in the area of material. Deep and systematic research on it plays an important role in solving the problem of hydrogen embrittlement, clarifying the mechanism of transition metal catalyzed hydrogen, and promoting the development of hydrogen storage materials and thermo-hydrogen treatment. This paper aims to clear the microscopic mechanism of metal-hydrogen interaction. The current research status of Metal-Hydrogen system using first-principles was reviewed in this paper. The effect of hydrogen on metal′s crystal structure, electronic structure, and mechanical properties as well as the adsorption and diffusion properties of hydrogen were summarized. Finally, the limitations of existing research were found and the future development of first-principles calculation of metal-hydrogen system was prospected.
