摘要

Controlled synthesis of structurally anisotropic rhenium diselenide (ReSe2) with macroscopically uniform and strictly monolayer thickness as well as tunable domain shape/size is of great interest for electronics-,optoelectronics-,and electrocatalysis-related applications.Herein,we describe the controlled synthesis of uniform monolayer ReSe2 flakes with variable morphology (sunflower-or truncated-triangle-shaped) on SiO2/Si substrates using different ambient-pressure chemical vapor deposition (CVD) setups.The prepared polycrystalline ReSe2 flakes were transferred intact onto Au foil electrodes and tested for activity in the hydrogen evolution reaction (HER).Interestingly,compared to the compact truncated-triangle-shaped ReSe2 flakes,their edge-abundant sunflower-shaped counterparts exhibited superior electrocatalytic HER activity,featuring a relatively low Tafel slope of ～ 76 mV/dec and an exchange current density of 10.5 μA/cm2.Thus,our work demonstrates that CVD-grown ReSe2 is a promising two dimensional anisotropic material for applications in the electrocatalytic HER.
