Facile Synthesis of FeOCl/Iron Hydroxides Hybrid Nanosheets: Enhanced Catalytic Activity as a Fenton-like Catalyst

Abstract

A facile rapid thermal annealing method to prepare FeOCl/Iron hydroxides hybrid nanosheets is reported. We first analyzed the exfoliation possibility of layered FeCl3•6H2O in theory. Then, the nanosheets were successfully obtained by using the rapid annealing to FeCl3•6H2O in experiment, which was FeOCl/Iron hydroxides hybrid. As a Fenton reagent, FeOCl/Iron hydroxides hybrid nanosheets showed outstanding properties in catalytic degradation of dye molecules in water at room temperature, under neutral pH conditions, and with visible light irradiation. Moreover, the hybrid nanosheets showed excellent structure stability. The degradation activity did not show decrease during four successive cycles. Apart from the increased surface area of nanosheets, the surface state change of the nanosheets also plays a key role in improving the catalytic performance and stability. The partial substitution of hydroxyl groups for chlorine on the surface promote the generation of OH• radicals and degradation of dye molecules.
