Abstract

Abstract

In view of the different coordination modes of different metal ions, it is difficult to synthesize bimetallic organic framework (MOFs) materials, and obtain bimetal oxides by directly calcining MOFs. In this paper, Cu₃(BTC)₂ was used as a material template to prepare metal oxide CuO, and Zn²⁺ calcination was introduced by light deposition to synthesize a bimetal oxide catalyst CuO/ZnO. And then the photocatalytic degradation performance for rhodamine B (RhB) was studied under visible light condition. The main active species of the rhodamine B was determined in the degradation process. The degradation mechanism of dyes was investigated by liquid phase in-situ infrared technology. The result showed the MOFs derivative CuO/ZnO catalyst had an excellent photocatalytic degradation ability. The degradation efficiency of 10 mg/L rhodamine B reached 67.56% above after 150 min of visible light response. Among them, superoxide radical·O₂^- played a major role. After 5 cycles, the degradation rate was still above 50%, which proved that the material had good reusability. A method of liquid phase in-situ infrared technology was established. The analysis result inferred that, during the degradation process, the destruction of the ethyl, carboxyl and benzene ring aromatic ring structure took place on the rhodamine B molecule, as well as the release of the amino by-products. The research results provide references for the development of high-efficiency photocatalytic system and researches on pollutant degradation mechanism.
