摘要

•Pt-V-W supported on TiO2 catalysts were prepared by co-impregnation method.•Simultaneous oxidations of NH3 and CO were characterized over Pt-V-W/TiO2.•Pt-V-W/TiO2 exhibited improved N2 selectivity compared to Pt/TiO2.•Pt-V interaction plays a role in active site of i-SCR and CO-SCR during oxidations.
