Mesoporous silicas were synthesized by condensation of tetraethoxysilane (TEOS) in the presence of Pluronic P123 as a structure-forming agent, and sucrose as an auxiliary agent, to investigate the effect of sucrose and aging temperature on the final properties, particularly structure-adsorption characteristics. Obtained materials have been characterized by XRD, nitrogen sorption measurements SEM-EDX, TEM, thermogravimetry, and FT-IR. The obtained materials have well-developed porous structure-values of the specific surface area (S BET ) are in the range of 300-950 m 2 /g and the sizes of primary mesopores are in the range of 9-11 nm. It was established that S BET and ordering significantly decreases with an increasing content of sucrose in the initial mixture.
