Nano-γ-Al2O3/SbCl5 as a new Lewis acid nano catalyst was synthesized and characterized by FTIR, XRD, FESEM, TEM, EDS, BET and TGA techniques. Nano-γ-Al2O3/SbCl5 has been employed for synthesis of 2-substituted perimidines via reaction of naphthalene-1,8-diamine with various aldehydes at room temperature under solvent-free conditions. This protocol proffers several benefits including high yields, easy

diameters of less than 100 nm are difficult to separate from the reaction mixture, therefore, magnetic nanoparticles (MNPs) were used as catalysts to overcome this problem. Fe3O4@NCs/BF0.2 as a green, bio‐based, eco‐friendly, and recyclable catalyst was synthesized and characterized using fourier‐transform infrared spectroscopy (FT‐IR), vibrating sample magnetometer (VSM), X‐ray diffraction (XRD), X‐ray fluorescence
纳米纤维素(NC)材料具有一些独特的特性,使其成为催化应用中的有机或无机载体具有吸引力。直径小于100 nm的纳米催化剂很难从反应混合物中分离出来,因此,磁性纳米颗粒(MNPs)被用作催化剂来克服这一问题。Fe 3 O 4 @ NCs / BF 0.2是一种绿色,生物基,生态友好且可回收的催化剂,并通过傅里叶变换红外光谱(FT-IR),振动样品磁力计(VSM),X射线进行了表征衍射(XRD),X射线荧光(XRF),Brunauer-Emmett-Teller(BET),场发射扫描电子显微镜(FESEM),透射电子显微镜(TEM)和热重分析(TGA)技术。铁3 O 4 @ NCs / BF 0.2用于在室温下在无溶剂条件下通过1,8-二氨基萘与各种醛的反应合成2,3-二氢-1H-亚氨基im衍生物。本方法具有几个优点,包括反应时间短,产率高,催化剂易于分离和环境友好。
