Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 N°20 (Octobre 2008) . - P. 7680-7685 Titre : Controlled synthesis of monolithic hierarchical porous materials using wood as a template with assistance of supercritical carbon dioxide Type de document : texte imprimé Auteurs : Jianbo Li, Éditeur scientifique ; Jiguang Wang, Éditeur scientifique ; Jianxia Jiao, Éditeur scientifique Année de publication : 2008 Article en page(s) : P. 7680-7685 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Carbon Dioxide Monolithic porous inorganic materials CO2 Résumé : A green and efficient process to synthesize monolithic porous inorganic materials with hierarchical structure has been presented. By using wood cellular structure as a template and supercritical CO2 as a solvent and carrier, the morphology and pore or channel systems of wood templates could be replicated faithfully. The total BET (Brunauer−Emmett−Teller) surface area of the resulting silica material can reach 469 m2/g using poplar as the template. It is found that different pore structure data can be obtained with different wood cellular structures as the template. Meanwhile, the pore structure data of the product can be adjusted by changing the experimental conditions of the supercritical CO2 during the impregnation process.
