Abstract

A novel MnO_x–TiO₂ catalyst with hollow silkworm structure was synthesized successfully via an ethanol-thermal strategy by using activated carbon fiber felt as template for the first time. The silkworm-like MnO_x–TiO₂ catalyst (MnTi) exhibited higher NO_x conversion in the whole experimental temperature region (90–330 °C) under a high space velocity of 36,000 h⁻¹ in comparison with the common MnO_x–TiO₂ catalyst without hollow silkworm structure (MnTi-B). The excellent catalytic performance of MnTi can be attributed to its high specific surface area, large content of active surface oxygen species (O_S), and more surface acid sites. In addition, the MnTi catalyst also exhibited excellent resistance to water or SO₂ poisoning.
