静置水解时间对Al-SBA-15介孔分子筛结构的影响

摘要

在磷酸介质中,以异丙醇铝为铝源,采用直接合成法合成出Al-SBA-15介孔分子筛.采用XRD、N2吸附-脱附、FT-IR等表征手段,考察了静置时间对Al-SBA-15介孔结构和性能的影响.%Using aluminum isopropoxide as aluminum source,Al-SBA-15 mesoporous molecular sieves was obtained directly in the presence of phosphoric acid.In order to investigate the effect of different static hydrolysis time,XRD,N2-BET and FT-IR techniques are adopted.
