Titanium nanotubes (TNTs)-confined ceria were for the first time prepared in this paper and used for selective catalytic reduction (SCR) of NO with ammonia. In comparison with the catalysts supported by TiO2 nanoparticles, the confined ceria showed a superiority in SCR of NO due to the improved redox potential and special adsorption of NH3, where its NO conversion could exceed 95% at reaction temperature of 270-500 degrees C, which was much higher than that of TiO2 nanoparticle supported catalysts.
