Redox and acid properties of MnV2Ox/TiO2 catalysts synthesized by assistance of microwave for NO selective catalytic reduction by ammonia

Supported manganese vanadate catalysts for selective catalytic reduction of NOx by ammonia (NH3-SCR) with wide temperature window were fabricated by assistance of microwave. Vanadate dispersed well on the surface of TiO2, giving an enhanced activity in a wide temperature range. The activity over the...
