The novel hybrid Co-aminobenzamid@Al-SBA-15 was synthesized as a modified mesoporous catalyst. To achieve this aim, the obtained materials were investigated by various techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N adsorption-desorption, field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) to examine the functional groups, crystallinity, surface area, morphology, particle size distribution and amounts of functional groups, respectively. Co-aminobenzamid@Al-SBA-15 exhibits excellent catalytic activity for the synthesis of 2,3-dihydroquinazolin-4(1)-ones under mild reaction conditions. The heterogeneous catalyst showed good recyclability and can be reused for ten consecutive cycles without significant loss of its catalytic activity.
合成了新型杂化的钴-氨基苯甲酰胺@Al-SBA-15作为改性介孔催化剂。为实现这一目标，采用包括傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、N吸附-脱附、场发射扫描电子显微镜（FE-SEM）和透射电子显微镜（TEM）等多种技术对所得材料进行研究，分别以考察官能团、结晶度、表面积、形态、粒径分布和官能团数量。钴-氨基苯甲酰胺@Al-SBA-15在温和反应条件下对2,3-二氢喹唑啉-4(1)-酮的合成表现出优异的催化活性。该多相催化剂显示出良好的可回收性，可连续重复使用十次而其催化活性无明显损失。
