Abstract
Abstract Experimental work on benzene oxidation over C, N doped-MnxOy species showed that the oscillation formation and utilization of sub-surface O2 species from the catalyst was the rate-determining factor for activity. The MnxOy species were synthesized using the biosynthesis method. Characterizations from XRD, XPS, H2-TPR, and In-situ DRIFT were employed to study their catalytic properties. The MnxOy@300 catalyst with low activation energy (Ea = 62 kJ/mol) and TOF of 0.035 h−1 showed the best performance. The kinetic and mathematical model was proposed based on the current results, and those from previous works. The Ea, heat of vaporization, and temperature included in the kinetic model, increased its efficiency. The parameters of the kinetic study were regressed and verified by experimental data and the oxidation route was simulated. The kinetic model was extended into a mathematical model to predict which parameters had the most effect on the C6H6 oxidation process.
