V2O5-decorated Mn-Fe/attapulgite catalyst with high SO2 tolerance for SCR of NOx with NH3 at low temperature

Magnetic γ-Fe2O3-Loaded Attapulgite Sorbent for Hg0 Removal in Coal-Fired Flue Gas

“…In addition, the surface of ATT can be used as a nucleation center to stabilize nanoparticles, leading to the formation of a uniform metal compound /ATT nano-composite 32,33 . There are increasing research efforts focusing on the modification of ATT as a catalyst for the selective catalytic reduction (SCR) of NOx in recent years [33][34][35] . However, few have investigated Hg 0 removal from coal-fired boiler flue gases by using ATT.…”

The remarkable promotional effect of SO2 on Pb-poisoned V2O5-WO3/TiO2 catalysts: An in-depth experimental and theoretical study

“…In addition to the pre-viously mentioned composite species, SO2 is also a common component of many industrial flue gas streams where the combustion of sulfur-containing fuels occurs. As such, these species have an important in-fluence on the performance of SCR catalysts [5][6][7][8]. Much of the pre-vious research investigating the mechanisms of deactivation of SCR catalysts are conducted in the absence of SO2, which may limit the understanding of the deactivation pathways of SCR catalysts under real conditions.…”

Research Status and Prospect on Vanadium-Based Catalysts for NH3-SCR Denitration

“…In view of the volatilization of vanadium at high temperatures, the use of metal vanadate (MeVO 4 ) in the active phase can increase the melting point of the catalyst [17,18]. Moreover, Zhou, X. et al [19] synthesize the V@Mn-Fe/ATP catalyst with a similar core-shell structure successfully. It was found that the V 2 O 5 layer as a coating might protect other active metals of the catalyst.…”
