Oxidation of ammonia to nitrogen over Pt/Fe/ZSM5 catalyst: Influence of catalyst support on the low temperature activity

► Pt/Fe/ZSM5 catalysts were tested for oxidation of NH3. ► Pt/Fe/ZSM5 catalysts showed good low-temperature activity for NH3 oxidation. ► Pt was exclusively dispersed on the Fe oxide through close Pt-Fe interactions. ► The degree of Pt-Fe interaction changed according to Fe loading amount.
