英文摘要	In our study, a series of sphere morphology of TiO(2)supports owned the different structural units, including the flower-like sphere with thin-long nanorods (TiO2-75), nanosheets-assembled sphere with broad-short nanorods (TiO2-50) and particle-assembled sphere (TiO2-30) which were synthesized with adjusting volume ratio of Titanium (IV) isopropoxide/acetic acid by solvothermal method. Subsequently, CeO2-WO3/TiO(2)catalysts were prepared by simple impregnation methods and applied for selective catalytic reduction of NO(x)with NH3. Notably, the TiO(2)sphere morphology gradually varied from flower-like sphere to particle-assembled sphere with the increase volume ratio of Titanium (IV) isopropoxide/acetic acid. Meanwhile, the microscopic structural units of morphology for TiO(2)support could be regularly controlled by adjusting volume ratio of Titanium (IV) isopropoxide/acetic acid. Among, the optimal flower-like sphere TiO(2)morphology with thin-long nanorods had the best catalytic performance when the volume ratio was 1:75, which could be attributed to bigger pore structure and higher specific surface area supplying enough dispersion for active ingredient, adsorption of reactants and exposure of more active sites. Meanwhile, it could be found that the redox ability and abundant surface acidity of the CeO2-WO3/TiO(2)catalyst played a critical role in catalytic activity via a series of characterizations.
