摘　　要：采用一锅法,在弱酸性水热条件下合成了具备优良结构的短孔道Zr-Al-SBA-15介孔分子筛,通过XRD、BET、pyridine FTIR、NH3-TPD、SEM、TEM,对所合成的催化剂的各种物理化学性质进行表征,并用于催化苯酚、甲醛合成双酚F。实验结果表明,对比传统的Al-SBA-15介孔分子筛,短孔道Zr-Al-SBA-15介孔分子筛表现出更好的催化活性和重复使用性,在适宜的反应条件(酚醛比30∶1、催化剂浓度0.004g·cm-3、反应时间60min、反应温度90℃)下,双酚F的收率高达96.1%。Short-channeled Zr-Al-SBA-15 with well-ordered mesostructures was prepared by a one-pot hydrothermal synthesis method under weak acidic condition.The physicochemical characteristics of the catalysts were characterized by XRD,BET,pyridine FTIR,NH3-TPD,SEM and TEM.Short-channeled Zr-Al-SBA-15 catalysts exhibited much higher catalytic activity and better reusability compared with the conventional Al-SBA-15.Under the suitable reaction conditions,a good yield to bisphenol F of 96.1%could be achieved over the solid catalyst.
