Abstract

This study investigates methanol partial oxidation over LaMnO3 and LaMn0.95B0.05O3 (B=Pd, Pt, and Rh) perovskites. Their bulk and surface properties were characterized by appropriate physiochemical techniques including BET surface area measurement, XRD, EDS, XPS, H2-TPR, O2-TPD, and CH3OH-TPD. The characterizations showed significant differences of reducibility and oxygen activity between promoted and untainted LaMnO3. Such deviants resulted in diverse catalytic behaviors in methanol partial oxidation. Promoted perovskites showed higher reactivity than pure LaMnO3. Moreover, the redox chemistry was proposed to enhance partial oxidation route to formaldehyde while oxygen activity, particularly surface chemisorbed oxygen, played a central role in combustion. Accordingly, plausible reaction mechanism of methanol partial oxidation over LaMnO3 based perovskites was elucidated.
