Title
In situ DRIFTS study on the partial oxidation of ethylene over Co-ZSM-5 catalyst
Abstract

The interaction of C2H4 and C2H4 + O2 with Co-ZSM-5 has been studied by in situ diffuse reflectance infrared fourier transform spectroscopy (DRIFTS). XRD, UV–vis and H2–TPR were used for characterizing the Co-ZSM-5 samples. DRIFTS results showed that a partial oxidation of ethylene over Co-ZSM-5 occurred at definite temperatures(⩾250 °C), leading to the formation of formate species in the presence or absence of gas phase oxygen. Investigation on active sites in Co-ZSM-5 by using NO as probe molecules revealed that a reduction of Co3+ to Co2+ occurred during reaction and Co3+ (presenting in Co3O4) were primarily responsible for the oxidation of ethylene.
