Porous Zeolitic Imidazolate Framework Loaded Mn as an Efficient Catalyst for the Selective Catalytic Reduction of NOx with NH3

Zinc 2-methylimidazolate (Zn(Me-Im)2, ZIF-8) was synthesized through solvothermal method, and the Mn@ZIF-8 by loading Mn species onto prepared ZIF-8 impregnation. The effect of addition amount for activity in selective catalytic reduction NOx with NH3 (NH3-SCR), stability catalysts at ideal temperature conditions resistance to H2O SO2 were investigated. Moreover, characterizations including XRD, SEM, EDS, XPS, BET, TGA H2-TPR carried out. results indicated that SCR related species, Mn@ZIF-8(0.8) showed best NO conversion over 90% ranging from 225°C-400°C good a long time test. Besides, high SO2. has great potential be an excellent support, is promising catalyst reaction.
