      Researchers from the Xiamen University have published a dissertation titled " Tunable optoelectronic and hydrogen evolution reaction properties of decorated 2D materials (Ga₂O₃ monolayer, ZnO monolayer and borophene)" in Physica E: Low-dimensional Systems and Nanostructures.

Abstract

      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.
