Abstract
In this paper, a MoSe2/TiO2 composite photocatalyst was constructed by modifying TiO2 with MoSe2 as a group catalyst. The results showed that pure TiO2 and MoSe2 had no degradation activity for RhB, and the composite catalyst of 0.03 g MoSe2 had the best photocatalytic degradation activity for RhB. Through SEM, TEM, UV-VIS absorption spectrum, transient photocurrent curve, photoluminescence spectrum, and electrochemical impedance spectrum analysis, it can be seen that the excellent performance of 0.03 g MoSe2 composite sample is due to its excellent nanostructure, and uniform TiO2 nanosheets are attached to MoSe2 flower spheres. The active site of RhB photocatalytic degradation was increased, the visible light response and photobiological carrier separation were enhanced, and TiO2 had photocatalytic activity under simulated sunlight.
期刊介绍:
Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and
appears with twelve issues per year. The journal is open to letters, short communications and breakings news
inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in
structure, properties and applications, as well as those covering special properties in nano-structured
chalcogenides are admitted.
