Effect of Mn substitution for Co in cobalt based mixed oxides on physical, chemical and catalytic properties in direct NO decomposition
Original language description
Nitric oxide together with NO2 are known as NOx, which are mainly produced by anthropogenic activities (combustion of fossil fuels in cars and industry) and its emissions represent serious environmental problems causing formation of photochemical smog and acid rains. Commonly used methods (selective catalytic reduction and selective non-catalytic reduction) are effective, however, reducing agent (NH3, urea) is needed.Co-based mixed oxides catalysts modified by K were found to be active in direct NO decomposition [1, 2] producing N2 and O2 as the final products. From our previous studies, it is known that addition of K ensures the required properties. Partial substitution of Co by Mg in K/Co4MnAlOx did not change the catalytic activity [3]. It suggests that Co, which is corrosive, toxic and expensive, can be replaced by another metal. In this study, Mn was used for the substitution of Co.
