Flexible Ti Mesh-Supported MnO_x–CuO_x/TiO₂ Nanosheet Monolithic Catalysts for Low-Temperature Selective Catalytic Reduction of NO_x with NH₃

In this work, we report the design and fabrication of flexible Ti mesh-supported MnO_x–CuO_x/TiO₂ nanosheet monolithic catalysts for NH₃–SCR in low temperature, which demonstrates considerable wide-temperature window and high N₂ selectivity. The flexible Ti mesh-supported MnO_x–CuO_x/TiO₂ nanosheet monolithic catalysts can achieve approximately 100% conversion of NO_x with high N₂ selectivity in the wide range of 145–300 °C and remarkable water resistance as well as long-term stability. This remarkable catalytic performance observed can be ascribed to the elevated specific surface area, robust synergistic interactions with Mn and Cu species, and substantial generation of Mn⁴⁺ and Cu²⁺. This work may provide more opportunities for practical applications of flexible Cu–Mn-based catalysts in diverse fields far beyond NH₃–SCR.
