- Abstract
The catalytic CO oxidation reaction has been investigated over a series of Mn/TiO catalysts. The titanium dioxides, including several mesoporous structures were prepared by different synthesis procedures. The mesoporous TiO synthesized using evaporation-induced self-assembly (EISA) method exhibited the highest surface area (217.14 m/g). The successful loading of the active manganese component (2 %) to TiO supports showed high dispersion of MnO species in amorphous state. Characterizations of XRD, N adsorption-desorption, pore size distributions, TEM, H-TPR and XPS were applied to contrast their structure properties and correlated with the corresponding catalytic performance. The Mn/EISA exhibited the highest catalytic activity among the series of Mn/TiO catalysts, which could completely oxidize CO into CO at temperature as low as 270 C, due to its highly ordered mesoporous channels, which effectively enlarge the surface area leading to promoting a strong interaction between MnO species (68 % Mn) and TiO support.
