Abstract
Employing “redox-precipitation” reactions among MnO4+, Fe2+, and Mn2+, a facile synthetic route for highly homogeneous FeMn oxide (Fe1Mn2-RP) has been developed, which can achieve a superior catalytic performance in toluene combustion with T50 and T90 of 186 and 197 °C, respectively (500 ppm toluene/humid air, GHSV = 50,000 h–1). XRD, N2 sorption isotherms, and TEM characterization demonstrated the formation of a homogeneous Fe-Mn-O solid solution with higher surface area for the Fe1Mn2-RP catalyst. The highly homogeneous Fe-Mn-O structure can result in better low-temperature reducibility and a higher amount of oxygen electrophilic species evidenced by H2-TPR and XPS, thus significantly increasing the catalytic activity. At the same time, the Fe1Mn2-RP catalyst showed excellent water/methanol-resistance and stability, demonstrating its great potential for practical application.
