摘要

采用硼酸熔融法制备富硼比金属硼酸盐ZnB₁₂O₁₄(OH)₁₀,并将其用于紫外光降解染料废水罗丹明B(RhB)的研究,通过多晶X射线衍射表征样品的结构。紫外-可见漫反射测试获得其光学带隙宽度约为4.0eV;光催化降解RhB实验表明,ZnB₁₂O₁₄(OH)₁₀在3h内对RhB的降解率高达65%,且降解机制符合赝一级动力学模型;循环光催化测试揭示,该富硼比硼酸盐具有较高的催化稳定性。

Abstract

The synthesis of boron-rich compound ZnB₁₂O₁₄(OH)₁₀ via boric acid flux method and its photocatalytic application of degrading the organic pollutant rhodamine (RhB) under UV light irradiation were reported.The structure was characterized by the powder X ray diffraction.The optic band gap 4.0eV was obtained by using diffuse reflectance spectroscopy.With the photo-catalyst ZnB₁₂O₁₄(OH)₁₀,more than 65% RhB was degraded under the UV light irradiation with 3 hours,and the dynamic reaction of degradation could be evaluated by the pseudo-first-order reaction model.Further,cycling photocatalytic experiment revealed that ZnB₁₂O₁₄(OH)₁₀ embraced relatively stable performance.This study offered a significant guidance to discover novel boron-rich photo-catalysts with excellent performance.
