Abstract

In this work, we report the design and fabrication of flexible Ti mesh-supported MnO x –CuO x /TiO 2 nanosheet monolithic catalysts for NH 3 –SCR in low temperature, which demonstrates considerable wide-temperature window and high N 2 selectivity. The flexible Ti mesh-supported MnO x –CuO x /TiO 2 nanosheet monolithic catalysts can achieve approximately 100% conversion of NO x with high N 2 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 Mn 4+ and Cu 2+ . This work may provide more opportunities for practical applications of flexible Cu–Mn-based catalysts in diverse fields far beyond NH 3 –SCR.
