A transient <i>in situ</i> infrared spectroscopy study on methane oxidation over supported Pt catalysts

Abstract

Catalysts with platinum dispersed on alumina, ceria and mixed alumina–ceria have been prepared by incipient wetness impregnation, characterized with transmission electron microscopy and X-ray diffraction, and evaluated for total oxidation of methane under both stationary and transient gas compositions (oxygen pulsing).
