Reaction Mechanism Dominated by the Hard–Soft Acid–Base Theory for the Oxidation of CH2Cl2 and CH3Br over a Titanium Oxide-Supported Ru Catalyst

In this study, the divergent behaviors were elucidated for CH2Cl2 and CH3Br oxidation over TiO2 and Ru/TiO2. Possible reaction mechanisms were elucidated. It was concluded that the adsorption and activation of halogenated volatile organic compounds were strongly dependent on the hard–soft acid–base theory.
