Reductive Activation of O2 with H2-Reduced Silver Clusters as a Key Step in the H2-Promoted Selective Catalytic Reduction of NO with C3H8 over Ag/Al2O3
The mechanistic cause of the dramatic activity improvement of alumina-supported silver (Ag/Al2O3) by H2 addition for the selective catalytic reduction of NO with propane (C3H8-SCR) was investigated… Expand
