摘要

采用水热法-水解法制备了BiOCl/PbBiO₂Cl异质结,利用XRD和SEM等表征其结构和光学性质;在紫外灯照射下,以甲基橙(MO)为目标污染物,探究了BiOCl/PbBiO₂Cl异质结的光催化行为。结果表明,当BiOCl与PbBiO₂Cl的物质的量比为1∶1时,所合成的花状BiOCl/PbBiO₂Cl异质结对MO的降解效果明显;且在处理100mL的10mg/L MO溶液时,0.15g该花状异质结对MO降解率达97.22%,明显优于单一PbBiO₂Cl催化剂。在此降解过程中,·O^-₂和h⁺是催化作用的主要活性物种。

Abstract

BiOCl/PbBiO₂Cl heterojunction was prepared by hydrothermal-hydrolysis method,and its structure and optical properties were characterized by XRD and SEM.Under UV light irradiation,the photocatalytic behavior of BiOCl/PbBiO₂Cl heterojunction was investigated with methyl orange (MO) as the target pollutant.The results showed that when the molar ratio of BiOCl to PbBiO₂Cl was 1∶1,the synthesized flower-like BiOCl/PbBiO₂Cl heterojunction exhibited significant degradation effect toward MO solution.Moreover,0.15g of the flower-like heterojunction heterojunction achieved a degradation ratio of 97.22% when treating 100 mL of 10mg/L MO solution,which was significantly better than that of the single PbBiO₂Cl catalyst.During the degradation process,·O^-₂ and h⁺ were the main active species responsible for the photocatalytic activity.
