英文摘要	NixCo1-xFe2Oz Compositeoxidenanosphere was successfully prepared, to degrade 2-monochlorobiphenly (CB-1) in continuous-flow fixed-bed microreactor at GHSV of 20000 h(-1). The five cycles of temperature-dependent run experiments between 150 and 350 degrees C showed its superior activity with a CB-1 conversion of more than 95% above 300 degrees C over Ni0.5Co0.5Fe2Oz Importantly, the sustainable higher reactivity could be observed over prolonged 600 min reaction times after the 5th run test. The degradation products detected as biphenyl and monochlorobenzene with yield ratio of 129, account for 0.24% and 0.0011% of initial CB-1 respectively. This indicated the weak occurrence of hydrodechlorination and breakage of C-C bridge bond during the degradation of CB-1. The possibly dominant occurrence of oxidative degradation probably follows Mars-van Krevelen mechanism, resulting in the generation of the formic, acetic, propanoic and butyric acids and so on. Due to the high oxygen mobility over Ni0.5Co0.5Fe2Oz nanosphere, the consumed oxygen species could be compensated rapidly by the gas phase oxygen via O-2 -> O-2(-) -> 2O(-) -> 2(2)(-). The interaction among different elements in Ni0.5Co0.5Fe2Oz nanosphere confirmed by the derivation of the electron cloud, enhanced the mobility of the reactive oxygen species, which would be beneficial for the oxidation of chlorinated biphenyls.
