Preparation of Porous Silica from TEOS-coated Activated Carbon in Supercritical CO2
Abstract:
Porous silica was prepared from tetraethyl orthosilicate (TEOS) coated activated carbon in supercritical CO2.The pore structure of the porous silica was determined.The multipoint BET surface area,total pore volume,and average pore size of the product prepared via supercritical CO2 coating were 1 147 m2/g),1.4 cm3/g and 2.20 nm,respectively.These results were better than that of the porous silica material prepared via simple immersion coating.In addition,the effects of various factors on the coating in supercritical fluids (SCF) were studied,and improved coating conditions were explored.
