Abstract

BifunctionalFe/ZrO2was prepared by mechanical mixing method, and its bifunctional effect on reductive dechlorination of chlorobenzene in subcritical water was studied. Dechlorination efficiency increased with increasing iron content in catalyst and catalyst amount. Dechlorination efficiency slowed when the iron content in catalyst reached 30%; bifunctional catalyst ofFe/ZrO2was more efficient in dechlorination of chlorobenzene thanFealone. Catalyst ofFe(30%)/ZrO2was characterized by means of X-ray diffraction (XRD),H2temperature programmed desorption (H2-TPD), andN2adsorption. The possible mechanism of dechlorination in subcritical water by this bifunctional catalyst was proposed.H+produced in the water dissociation formed the highly reactive spillover hydrogen on the surface of catalyst, and then reacted with chlorobenzene adsorbed on the catalyst surface byZrO2to form benzene and chloride ions.
