The influence of the concentrations of NO and O₂ on the oxidation of NO was investigated. Besides, the changes in the reaction rate with the particle size of the catalysts were investigated to determine the internal diffusion resistance. The surface area and microcrystalline structure of the catalysts were analyzed to investigate the impact of physical structure on SO₂ poisoning in the catalyst. It was observed that Co doping in Mn/TiO₂ had a favorable impact on reducing the effect of SO₂ poisoning during the NO oxidation reaction. On the basis of the kinetic study, it was concluded that the reaction followed the Langmuir−Hinshelwood (L-H) mechanism, where NO and O₂ were adsorbed on the catalyst, forming highly reactive NO⁺ and O⁻, which were then converted into NO₂. The Co doping into the TiO₂ crystal lattice increased the O₂ adsorption, thus accelerating the rate of NO oxidation reaction.]]> Fri 22 Jul 2022 13:14:04 AEST ]]>
