Fabrication of MOF(Fe)/FeS x composite as efficient photocatalyst for degradation of rhodamine B

Abstract

Abstract With the development of science and technology, the living standards of human beings have been greatly improved. However, the rapid development of society caused serious environmental pollution issues, especially coming from the organic materials. In this paper, MOF(Fe)/FeSx composite were successfully fabricated via solvothermal method by adopting MOF(Fe) as template and thioacetamide as sulfur source, and its photocatalytic activity was evaluated by degradation of rhodamine B (RhB) under UV light irradiation. The influence of thioacetamide on the photocatalytic activity of MOF(Fe)/FeSx composite was explored. The results shown that MOF(Fe)/FeSx(2) exhibited the optimal photocatalytic degradation performance. After 35 min UV irradiation, MOF(Fe)/FeSx(2) could degrade 97.19% of rhodamine B (RhB). The excellent photocatalytic degradation performance of MOF(Fe)/FeSx(2) made it potential to be used for the degradation of organic pollutants produced in factories and daily life.
