Abstract

In this paper, a novel improvement in the catalytic Fenton reaction system named MHACF-NH$_{2}$-MIL-101(Cr) was constructed based on H$_{2}$ and Pd/NH$_{2}$-MIL-101(Cr). The improved system would result in an accelerated reduction in Fe$^{III}$, and provide a continuous and fast degradation efficiency of the 10 mg L$^{-1}$ 4-chlorophenol which was the model contaminant by using only trace level Fe$^{II}$. The activity of Pd/NH$_{2}$-MIL-101(Cr) decreased from 100% to about 35% gradually during the six consecutive reaction cycles of 18 h. That could be attributed to the irreversible structural damage of NH$_{2}$-MIL-101(Cr). Key words:
