Abstract:

The low temperature NOx elimination properties of both single or multi-transition metal manganese-based catalysts and supported single or multi-transition metal manganese-based catalysts were summarized.The influence of transition metal catalysts with different structures prepared under different active components on denitration activity was emphatically expounded.The reaction mechanism of transition metal catalyst in low temperature NH3-SCR and its sulfur and water resistance were analyzed and summarized.Finally,aiming at present problems,the potential development direction and research hotspot of tran sition metal catalysts in the future were prospected.

Key words: transition metal, low-temperature SCR, sulfur and water resistance, denitration mechanism
