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 MnOx-CuOx/TiO2 nanosheet monolithic catalysts for NH3-SCR in low temperature, which demonstrates considerable wide-temperature window and high N-2 selectivity. The flexible Ti mesh-supported MnOx-CuOx/TiO2 nanosheet monolithic catalysts can achieve approximately 100% conversion of NOx with high N-2 selectivity in the wide range of 145-300 degrees 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.
