Abstract

Abstract:

In order to optimize the structure of BiOCl photocatalyst, improve its adsorption performance to organic pollutants, and enhance photocatalytic activity, BiOCl/montmorillonite(MMT) composite photocatalyst was prepared by ultrasonic assisted chemical precipitation method. The influence of composite mass fraction of montmorillonite(w(MMT)) on its photoactivity was investigated. The characterization results of XRD, SEM, FTIR and DRS show that the obtained composite catalyst has a microsphere structure with a band gap of 3.24 eV. With the increase of w(MMT), the microsphere structure of the composite catalyst is gradually destroyed, but the band gap energy does not change significantly. The adsorption and photocatalytic activity of the composite catalyst were investigated with 8-hydroxyquinoline as the target. The results show that with increase of w(MMT), the adsorption and photocatalytic oxidation activity of 8-hydroxyquinoline is gradually increased, which can be attributed to the increased specific surface area and reduced photo-generated carriers' recombination efficiency due to the composite of montmorillonite. When w(MMT) is 15%, the adsorption and photocatalytic performance of the catalyst are optimal. After 50 min of illumination, the degradation rate of 8-hydroxyquinoline reaches 85.6%, and the mineralization rate reaches 51.0%. Photogenerated holes and superoxide radical anions are the main oxidation active species. The composite catalyst also efficiently degrades catechol and p-aminobenzoic acid. At the same time, the composite photocatalyst exhibits strong chemical stability, indicating that it has strong practical application value and can be used for treating industrial wastewater containing organic phenolic pollutants.

Key words: BiOCl, montmorillonite, 8-hydroxyquinoline, photocatalysis, mineralization
