Abstract

Gas adsorption techniques have been used to study the pore texture changes occurring in composite SnO2-CeO2 materials of varying Sn: Ce atom ratios on calcination at temperatures up to 1273K. The data show that the uncalcined materials are largely microporous in nature, but changes in specific surface area, pore sizes and pore volume occur at an early stage in the calcination process with the formation of mesopores. However, significant changes occur at calcination temperatures>673 K at which point the mesopores are substantially reduced, and at 873 K and above the mean pore size increases greatly finally giving non-porous solids after calcination at 1273 K.
