β-In₂Se₃ is widely used in various fields due to its good mobility and excellent photoresponse.However,Due to the fact that In₂Se₃ has multiple complex crystal structures and indium is prone to hydro-lysis,it is difficult to prepare layeredβ-In₂Se₃ in solution.Using InCl₃,Se powder and ethylenediamine as raw materials,β-In₂Se₃ powder was prepared by the solvothermal method.The structure,morphology and optical properties of the powder were characterized by Raman spectrometer,Fourier infrared spectrometer,thermogravimetric analyzer,scanning electron microscope and fluorescence spectrophotometer.The photocatalytic properties of the powders were investigated using methyl orange solution as the degradation substance.The results show that the main component of the prepared powder isβ-In₂Se₃ with a layered structure.The powder has good absorption in the UV and visible light regions,with an optical bandgap of approximately 2.01 eV,and has excellent fluorescent properties.β-In₂Se₃ powder exhibits photocatalytic activity towards methyl orange,and after 5 h of UV irradiation,the degradation rate of methyl orange can reach 81%.The result expands the application ofβ-In₂Se₃ for the degradation of organic pollutants.
