Exploring some Aliphatic Dicarboxylate Iron based MOFs on the Fenton and Photo-Fenton like Degradation of Methylene Blue

H. Bhasin | P. Kashyap | Dr. D. Mishra

Abstract: Four iso-structural Fe-MOFs based on aliphatic di-carboxylate linkers were synthesized to employ as peroxidase like catalyst for fenton and photo-fenton like degradation of methylene blue (MB) in water. The synthesized MOFs were characterized using SEM, FTIR, PXRD and BET. The reaction parameters that affect MB degradation were investigated such as pH of the solution, concentration of catalyst and H2O2 concentration, linker chain effect, and temperature. The results exhibit a wide range of working pH (3-11), temperature tolerance and good recyclability for MB removal in wide pH range. Scavenger insertion and fluorescent probe (UV_VIS) results suggest the involvement of hydroxyl radicals in MB degradation. These findings provide a new insight into the application of highly efficient synthesized Fe-MOFs based fenton and photo-fenton like heterogeneous catalysts and linker chain effect for their enhanced application.
