中文摘要	Herein mesoporous CeO/sub 2/ with high thermal stability was synthesized via a new hydroxycarbonates based hydrothermal treatment approach in present of hexadecyltrimethylammonium bromide (CTAB). IR and XRD prove the coexistence of hydroxycarbonate cerium and CTAB in precursors. TEM micrographs show that non-ordered pore structure is formed in the product, and average particle size of 20 nm is obtained even after calcined at 1173 K. BET results exhibit that the pore structure is stable when the calcination temperature is below 923 K. However, while calcinated at 1173 K, the average particle size is 20 nm, the BET surface area and pore volume can remain as high as 31.07 m/sup 2 //g and 0.21 cm/sup 3/g/sup -1/.
