Review of the Catalytic System, Synthetic Process, and Support Morphological Research in Selective Catalytic Oxidation of Ammonia

Catalytic NH3 oxidation affected by the nanometric roughness of the platinum overlayer

“…1,2 Another illustrative example is the catalytic NH 3 oxidation essential for NH 3 slip catalysis (ASC). 9–12 It is widely acknowledged that Pt is among the most active catalysts, especially at low temperatures (≤200 °C) in the presence of water vapour (∼10 vol%). 13–21 A few-nanometre-thick Pt overlayer on the metal foil substrate exhibited NH 3 oxidation activity comparable to or even superior to Pt nanoparticle catalysts like Pt/γ-Al 2 O 3 .…”
