Cerium-incorporated ordered porous zirconia materials have been prepared by the surfactant-assisted route and a post-grafting method. The X-ray powder diffraction, TEM, nitrogen adsorption and UV-Vis spectroscopy were adopted for the characterization of the synthesized materials. It is shown that small amount of cerium has been successfully incorporated into the framework of zirconia, and the surplus...
Pure and boron-doped γ-Al 2 O 3 membranes have been synthesized by the sol-gel method. The thermal stability of the unsupported alumina membrane was studied by determining the pore structure (including average pore size, pore volume and BET surface area). The average pore size of the pure alumina membrane increased sharply after sintering at temperatures higher than 1000 o ...
