The Construction of Accelerated Catalytic Fenton Reaction Based on Pd/MIL-101(Cr) and H2

Abstract

A novel catalytic Fenton system based on H2 and solid catalyst Pd/MIL-101(Cr) (MHACF-MIL-101(Cr)) was developed at normal temperature and pressure. In this system, the reduction process of FeⅢ back to FeⅡ was accelerated significantly. With using only trace level FeⅡ at the beginning of the reaction, the MHACF-MIL-101(Cr) provided continuously production of hydroxyl radicals and rapidly degradation of the model contaminant 10mg•L-1 4-chlorophenol in the initial condition of pH 3, 25μM FeⅡ, 25mM H2O2, 85 mL•min-1 H2 and 2g•L-1 Pd/MIL-101(Cr). The activity of solid catalyst gradually decreased from 100% to about 70% during the 6 consecutive degradation reaction cycles of 18h. That may mainly attribute to the structural damage and the surface area reduction of this catalyst.
