Controlling the FeO-SiO interaction: The effect on the HS selective catalytic oxidation and catalyst deactivation.

Biogas utilization is one of the most promising options for reducing the consumption of fossil fuels for energy production, but the presence of HS represents a serious industrial and environmental problem. In this work, two different synthesis methods (sol-gel and incipient wetness impregnation) were used to synthesize iron oxide supported on silica catalysts (FeO/SiO) with metal loadings ranging from 0.5 to 10 %wt.
