Low-temperature　selective　catalytic　reduction　(SCR)　is　important　for　the　elimination　of　NOx　from　stationary　sources.　In　the　present　study,　the　loading　of　Ce　and　W　on　α-Fe2O3　was　achieved　through　the　integration　of　single-mode　microwave　and　incipient　wetness　impregnation　(IWI)　methods.　The　scanning　electron　microscopy　(SEM)　and　transmission　electron　microscopy　(TEM)　images　reveal　that　the　structure　of　α-Fe2O3　is　spindle-like,　and　the　structure　remains　unchanged　after　the　introduction　of　Ce　and/or　W.　The　results　of　NH3-SCR　investigation　demonstrate　that　NOx　conversion　over　Ce–W/α-Fe2O3　is　more　than　85%　at　300　°C,　which　is　much　higher　than　that　over　Ce/α-Fe2O3　and　α-Fe2O3.　Our　studies　illustrate　that　the　addition　of　Ce　can　significantly　increase　the　amount　of　surface　oxygen　vacancies　as　well　as　sites　of　moderate　basicity.　On　the　other　hand,　the　addition　of　W　can　obviously　decrease　the　amount　of　basic　sites　and　increase　the　number　of　Brønsted　acid　sites.　The　synergistic　effect　of　Ce　and　W　addition　on　balancing　acidity/basicity　properties　accounts　for　the　high　activity　of　Ce20W10/α-Fe2O3　for　NOx　removal　at　low　temperatures.　The　study　provides　insight　into　the　relationship　between　acidity/basicity　properties　and　catalytic　performance　of　Ce–W/α-Fe2O3　catalysts,　which　is　beneficial　to　the　design　of　high-performance　NH3-SCR　catalyst　for　NOx　removal　at　low　temperatures.　©　2022　Chinese　Society　of　Rare　Earths
