Toluene and 2-propanol mixture oxidation over Mn2O3 catalysts: Study of inhibition/promotion effects by in-situ DRIFTS
Chemical Engineering Journal(2023)
摘要
•Mn2O3 oxides are active for the oxidation of toluene, 2-propanol and their mixture.•Mn2O3 catalyst prepared by Citrate-Gel method has the best catalytic performances.•The presence of both VOCs promoted the deep oxidation of each other on Mn2O3.•The promotion effect of binary mixture above 200 °C was proven by in-situ DRIFTS.•DRIFTS allowed to identify the reaction intermediates in different scenarios.
