Heterogeneous Fenton oxidation of nitric oxide by magnetite: Kinetics and mechanism

Magnetite materials were used for catalytic decomposition of peroxide hydrogen since Fe2+ can react with peroxide hydrogen directly to generate OH rather than Fenton-like reaction. The purpose was to determine the NO oxidation under various working conditions. The features of fresh and used catalysts was analyzed according to XRD and XPS. In addition, the reaction conform to a pseudo-first order kinetics pattern on the basis of results. The rate constants was calculated by different results and the activation energy for the reaction was obtained as 32.07 kJ/mol.
