مستخلص: | Transition metal oxides are frequently used as catalysts for NO selective catalytic reduction by CO (CO-SCR), but their catalytic activity is limited by the content of active metal species, the lower surface area, and the underdeveloped pore structure. Herein, we prepared three MOF-derived materials (Cu/C, Cu-CuOx/C, and CuO/C), in which active copper species (Cu0, Cu+, and Cu2+), specific surface areas, and porosity were modulated through different heat treatment conditions. Moreover, these composite materials can be used as efficient catalysts for CO-SCR. In particular, it is demonstrated that the Cu/C catalysts containing only Cu0 species could exhibit 100% NO conversion from 350 °C to 500 °C, nearly 100% N2 selectivity, and devoid of any by-product N |
