Synthesis and characterization of Ce-doped mesoporous anatase with long-range ordered mesostructure

The effect of cerium cation on the formation of titania crystallites using H+ as catalyst under mild condition has been investigated. The results indicated that the presence of cerium cation can improve the selectivity of producing anatase crystallites and inhibit the growth of crystallites. The Ce-doped mesoporous titania with highly crystallized pore walls consisting of anatase nanoparticles was synthesized by anatase crystallites assembly. The long-range ordered mesostructure was characterized by low angle and wide angle X-ray diffraction (XRD), N2 adsorption–desorption, transmission electron microscopy (TEM) and selected area electron diffraction (SAED).
