Performance Study of MIL-53(Fe)and Its Doped Variants as Potential Photo catalysts.

Abstract

This work includes synthesis of MIL-53 (Fe) metal organic framework and its doped derivatives (Li, Na, K) using microwave technique. Various characterization techniques like SEM, PXRD, TGA, FT-IR and UV-Vis reflectance detailed the physical, thermal and electronic properties of the synthesized materials. MIL-53-(Fe) was found to be stable up to 330?C and fairly stable in the aqueous environment where pH was ranging from 2-11. MIL-53 (Fe) along with its cation doped variants were found to be photo catalytically active and the activity decreased in the following order: MIL-53-(Fe) > MIL-53-(Fe) Li > MIL-53-(Fe) K > MIL-53-(Fe) Na; both in presence as well as in absence of an electron acceptor (H2O2). MIL-53 (Fe) showed degradation efficiency of approximate 86% and in presence of H2O2 as an enhancer it was increased to 96%.
