We have successfully incorporated iron species into mesoporous aluminosilicates (AlSBA15) using a simple mechanochemical milling method. The catalysts were characterized by nitrogen physisorption, inductively coupled plasma mass spectrometry (ICP-MS), pyridine (PY) and 2,6-dimethylpyridine (DMPY) pulse chromatography titration, powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX). The catalysts were tested in the N-alkylation reaction of aniline with benzyl alcohol for imine production. According to the results, the iron sources, acidity of catalyst and reaction conditions were important factors influencing the reaction. The catalyst showed excellent catalytic performance, achieving 97% of aniline conversion and 96% of imine selectivity under optimized conditions.
我们成功地使用简单的机械化学研磨法将铁物种掺入中孔硅铝酸盐（AlSBA15）中。通过氮气物理吸附、电感耦合等离子体质谱（ICP-MS）、吡啶（PY）和 2,6-二甲基吡啶（DMPY）脉冲色谱滴定、粉末 X 射线衍射（XRD）、X 射线光电子能谱（XPS）和带有能量色散 X 射线光谱仪的扫描电子显微镜（SEM-EDX）对催化剂进行了表征。我们在苯胺与苄醇的 N-烷基化反应中测试了这些催化剂用于亚胺的生成。根据结果，铁源、催化剂的酸度和反应条件是影响反应的重要因素。在优化条件下，催化剂表现出优异的催化性能，苯胺转化率达到 97%，亚胺选择性达到 96%。
