Abstract

Ordered SBA-15 with a high specific surface area, large pore size and pore volume could be synthesized at a short time (overnight) without further calcination. During the SBA-15 synthesis process, TEOS hydrolysis, the condensation of the silica species and the decomposition of the Pluronic P123 template were completed by using sulphuric acid. The decomposed Pluronic P123 could be completely exacted by solvent after synthesis. SBA-15 had high hydrothermal stability.
