![]() ![]() ![]() It was supposed that the loading of the Co3O4 dopant not only increased the content of oxygen vacancies in the catalyst but also increased the specific surface area and pore volume of the CuO/α-MnO2 nanowire catalyst, which would further enhance the catalytic activity. Further catalyst characterization showed that the CuO/α-MnO2 catalyst modified with 3 wt% Co3O4 and calcined at 400 ☌ performed the highest CO catalytic activity (T90 = 75 ☌) among the investigated catalysts. The effects of the loaded transition metal type, the loading amount, and the calcination temperature on the catalytic performances were systematically investigated. nanowire catalysts were prepared by the deposition precipitation method for catalytic CO oxidation reactions. In this study, a series of transition metal oxides (Fe2O3, Co3O4 and NiO) promoted CuO-based catalysts supported on the α-MnO2. The CuO-based catalysts have been widely investigated due to their availability. Therefore, the thermally catalytic oxidation of CO has received extensive attention in recent years. As a toxic pollutant, carbon monoxide (CO) usually causes harmful effects on human health. ![]()
