Hydrothermal Synthesis of SBA-15 Using Sodium Silicate Derived from Coal Gangue

الملخص EN

Well-ordered SBA-15 was prepared with a hydrothermal route by sodium silicate derived from coal gangue.

The as-prepared sample was analyzed by SAXRD, BET, TEM, and SEM, respectively.

The results indicate that at a low hydrothermal temperature of 100∘C the well-ordered mesoporous SBA-15 could be synthesized.

The surface area, pore volume, and pore size of the sample are 552 m2/g, 0.54 cm3/g, and 7.0 nm, respectively.

It is suggested that coal gangue could be used in obtaining an Si source to prepare mesoporous materials, such as SBA-15.
