摘要

In this study, we reported a remarkably improved catalytic activity of Mn/γ-Al₂O₃ catalyst promoted with potassium doping in the selective oxidation of benzyl alcohol with molecular oxygen. Characterizations of powder X-ray diffraction (XRD), Raman spectroscopy, X-ray absorption fine structure (XAFS), and hydrogen temperature-programmed reduction (H₂-TPR) revealed that the co-impregnation of potassium to the Mn/γ-Al₂O₃ gave rise to the presence of α-MnO₂ rather than β-MnO₂, resulting in a stable catalyst with enhanced catalytic performance. We also demonstrated this alumina-supported K-Mn mixed oxide catalyst can effectively catalyze aerobic oxidation of various aromatic alcohols.
