摘要
A simple synthesis method is presented to prepare highly ordered novel P-SBA-15 materials, which can provide additional Bronsted acid sites for potential applications in catalysis. The developed materials have been unambiguously characterized by various techniques such as SAXS, nitrogen physisorption, SEM, TEM, (31)PNMR and FT-IR spectroscopy. The SAXS and TEM results revealed well-ordered hexagonal arrays of mesoporous materials. (31)PNMR and EDS results confirmed the incorporation of phosphorous in the SBA-15 network. The method can provide an efficient way to synthesize high phosphorous content mesoporous silica with ordered structure.
