Novel CuO$ TiO_{2} $ Core–Shell Nanostructure Catalyst for Selective Catalytic Reduction of $ NO_{x} $ with $ NH_{3} $
CuO$ TiO_{2} $ core–shell nanostructure catalyst with CuO core and $ TiO_{2} $ shell was prepared by a two-step method and then used in $ NH_{3} $-SCR reaction. FE-SEM, TEM and element mapping were used to investigate the morphologies of the sample. Their results indicated CuO nanorods were coated w...

Novel CuO$ TiO_{2} $ Core–Shell Nanostructure Catalyst for Selective Catalytic Reduction of $ NO_{x} $ with $ NH_{3} $ |
| abstract |
CuO$ TiO_{2} $ core–shell nanostructure catalyst with CuO core and $ TiO_{2} $ shell was prepared by a two-step method and then used in $ NH_{3} $-SCR reaction. FE-SEM, TEM and element mapping were used to investigate the morphologies of the sample. Their results indicated CuO nanorods were coated with $ TiO_{2} $ and thus forming a core–shell nanostructure. According to the results of $ N_{2} $ adsorption–desorption, XRD, Raman, XPS, $ NH_{3} $-TPD, $ H_{2} $-TPR and in situ DRIFTS, the core–shell nanostructure would benefit the formation of better redox ability, more oxygen vacancies, more acid sites and abundant adsorbed $ NO_{x} $ species on the catalyst. Thus, the core–shell nanostructure catalyst presented significantly higher activity than pure CuO and $ TiO_{2} $. $ NH_{3} $-SCR reaction on CuO@$ TiO_{2} $ core–shell catalyst should follow both Eley–Rideal (E-R) mechanism and Langmuir-Hinshewood (L–H) mechanism. These findings may promote the development of the new effective non-vanadium-based SCR catalysts.
