Аннотация: A simple and convenient templating approach for the preparation of metal-oxide catalysts and supports has been studied. The method, based on the absorption of an aqueous solution of metal salts by cellulose material, followed by drying and combustion of the organic matrix, leads to the formation of high-surface area mesoporous mateПоказать полностьюrials with unusually high thermal stability. Examples include Ce-Zr mixed oxides (BET surface areas of 90-130 m(2)/g after calcination at 800 degreesC for 2h; 21-30 m(2)/g after 12h at 1050 degreesC) and La-stabilized alumina (BET surface areas of 275-320 m(2)/g after calcination at 800 degreesC for 2 h, 88-141m(2)/g after 12 h at 1050 degreesC). The pore-size distribution, morphology, and the effect of preparation parameters on surface area are discussed. (C) 2001 Elsevier Science B.V, All rights reserved.
