Flexible Ti Mesh-Supported MnOx–CuOx/TiO₂ Nanosheet Monolithic Catalysts for Low-Temperature Selective Catalytic Reduction of NOx 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 N2 selectivity. The flexible Ti mesh-supported MnOx–CuOx/TiO2 nanosheet monolithic catalysts can achieve approximately 100% conversion of NOx 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.
