Pt/COF-LZU1中空结构催化剂的制备及其催化性能
Preparation and catalytic performance of hollow Pt/COF-LZU1 catalyst
摘要
Abstract
In order to improve the removal efficiency of azo dyes,the hollow Pt/COF-LZU1 catalyst was prepared by the combination of heating reflux,etching and impregnation.The morphology and structure of the catalyst were characterized,and its catalytic decomposition of methylene blue solution was investigated.The results show that when the ratio of silica microspheres,homophentriformaldehyde and p-phenylenediamine is 1∶1∶1,the hollow COF-LZU1 microspheres have better dispersion and no redundant COFs chains are formed on the surface.Moreover,the Pt/COF-LZU1 catalyst has large loading amount of Pt nanoparticles and uniform distribution.At room temperature,the catalytic decomposition efficiency of 40 mg Pt/COF-LZU1 hollow catalyst+H2O2 for 150 mL 10 mg/L methylene blue can reach 93.45％after 120 min.关键词
