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.
