摘要

二维（2D）材料由于其独特的物理性质，在下一代技术应用中受到了相当大的关注。本文报道了具有高可见光吸收能力和析氢反应（HER）催化性能的修饰单层膜（O-V-Ga2O3-m， Co掺杂ZnO-m和Fe cluster@Borophene）。应变和电场可以精确调节O-V-Ga2O3-m、Co掺杂ZnO-m和Fe cluster@Borophene的光学和HER性质。结果表明，随着应变的增加或电场的增加，可见光区的吸收峰发生红移。应变和电场都可以调制修饰单层膜可见光区的吸收峰，从而获得最佳的she性能。这些特性促进了O-V-Ga2O3-m、Co掺杂ZnO-m和Fe cluster@Borophene在光电器件和HER电催化剂中的有效应用。

Tunable optoelectronic and hydrogen evolution reaction properties of decorated 2D materials (Ga2O3 monolayer, ZnO monolayer and borophene)

Two-dimensional (2D) materials have received considerable attention for next-generation technological applications due to their unique physical properties. Herein, decorated monolayers (O-V-Ga₂O₃-m, Co doped ZnO-m and Fe cluster@Borophene) with high visible light absorption ability and hydrogen evolution reaction (HER) catalytic performance are reported. Strain and electric field could precisely tune the optical and HER properties of O-V-Ga₂O₃-m, Co doped ZnO-m and Fe cluster@Borophene. It is shown that the absorption peaks in the visible region red-shift with the increasement of strain or adding electric field. Both strain and electric field can modulate the absorption peaks of decorated monolayers in the visible zone and help to obtain optimal HER performance. These features advocate effective applications of O-V-Ga₂O₃-m, Co doped ZnO-m and Fe cluster@Borophene in optoelectronic devices and HER electrocatalysts.
