Abstract
In the present research work, a novel catalyst based on natural material, namely, FeO@nano-almondshell@OSi(CH)/NHCHpyridine/Cu abbreviated (FNAOSiPAMP/Cu) was designed and prepared. The properties of the catalyst was identified by Fourier-transform infrared spectroscopy (FT-IR), Thermogravimetry ananlysis (TG), X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), and Mapping. Furthermore, the evaluation of catalytic activity was done in the course of naphtho-1,3-oxazines synthesis. Solvent-free conditions, simplicity of operation, easy work-up and use of an eco-friendly catalyst are some of advantages of this protocol.
摘要
在本研究工作中，设计并制备了一种基于天然材料的新型催化剂，即 FeO@纳米杏仁壳@OSi(CH)/NHCHpyridine/Cu 缩写为 (FNAOSiPAMP/Cu)。通过傅里叶变换红外光谱 (FT-IR)、热重分析 (TG)、X 射线衍射 (XRD)、能谱 (EDS)、场发射扫描电子显微镜 (FESEM)、透射电子显微镜 (TEM) 和 Mapping 对催化剂的性能进行了鉴定。此外，还在萘并[1,3]恶嗪合成过程中对催化活性进行了评价。无溶剂条件、操作简单、后处理简单以及使用环保催化剂是该方案的一些优点。
