A series of praseodymium added CeO₂（ZrO₂）/TiO₂ catalysts separately prepared by methods of sol-gel and impregnation were tested for selective catalytic reduction of NO, and characterized by X-ray diffraction（XRD）, N₂-brumauer-emmett-teller（N₂-BET）, NH₃-temperature programmed desorption（NH₃-TPD）, H₂-temperature programmed reduction（H₂-TPR）, PL spectra, Raman spectra, electron paramagnetic resonance（...
