Facile synthesis of hierarchical Ti3C2/Bi12O17Br2 Schottky heterojunction with photothermal effect for solar-driven antibiotics photodegradation
摘要
Abstract
Photocatalytic technology is considered to be an efficient and green approach for removing tetracycline hydrochloride(TC)to meet the demands of sustainable development.Here,a facile stirring process was employed to construct Ti3C2/Bi12O17Br2(termed as TBOB)Schottky heterojunction with a hierarchical structure,in which the Bi12O17Br2 component was closely deposited on the surface of Ti3C2.The TC photodegradation performance was estimated for all catalysts under simulated solar light.Compared with Bi12O17Br2,TBOB materials exhibited the superior photodegradation activity due to the synergistic effect between Ti3C2 and Bi12O17Br2,which could increase light harvesting capacity derived from Ti3C2 loading,promote the charge carrier separation due to the formed Schottky heterojunction,and facilitate surface reaction kinetics owing to the photothermal effect.Besides,some crucial influencing factors on the photocatalytic performance over TBOB composites were separately studied in detail.The free radical capture experiment and electron paramagnetic resonance(EPR)technique confirmed the predominant active species of·O2-and e-for the TC photodegradation.Combined with experimental analysis and theoretical calculations,insight into the charge carrier transfer and photodegradation mechanisms were proposed.This study provides theoretical and experimental insights for the rational design of high-efficiency photothermal-assisted Ti3C2-based photocatalysts.关键词
