使用共沉淀法分别制得镁铝水滑石固载MnO4-、Cr2O72-催化剂HT-MnO4-、HT-Cr2O72-和IO4-柱撑型催化剂HT-IO4-,并在温和条件下用于以分子氧为氧化剂的醇类催化液相氧化反应,结果表明HT-MnO4-、HT-Cr2O72-催化剂可以在温和条件下实现醇类化合物(苯甲醇、对甲氧基苯甲醇、2-吡啶甲醇、肉桂醇、苯乙醇)的高选择性氧化转化。XRD表征给出水滑石经过MnO4-、Cr2O72-阴离子交换以后,X射线衍射峰中最强峰对应晶面的平均粒径减小,但结构仍然完整;XPS表征表明HT-MnO4-、HT-Cr2O72-中Mn、Cr的结合能较之KMnO4、K2Cr2O7中Mn、Cr的结合能有所降低。
MgO-hydrotalcite-supported MnO4-, Cr2O72-catalyst HT-MnO4-, HT-Cr2O72- and IO4-pillared catalyst HT-IO4- were respectively prepared by coprecipitation method and were used under mild conditions for molecular oxygen The results showed that the catalysts HT-MnO4- and HT-Cr2O72-catalyzed alcohols (benzyl alcohol, p-methoxybenzyl alcohol, 2-picolyl alcohol and cinnamyl alcohol , Phenethyl alcohol). XRD characterization shows that the average grain size of the strongest peaks in the X-ray diffraction peak of the hydrotalcite decreases after MnO4-, Cr2O72- anion exchange, but the structure is still intact. The XPS characterization shows that the average particle sizes of HT-MnO4- and HT-Cr2O72- The binding energy of Mn and Cr is lower than that of KMnO4 and K2Cr2O7.
