nanoparticles: Magnetically recoverable catalyst for the one‐pot synthesis of polyhydroquinoline
synthesized materials. The BiFeO3 nanoparticles so obtained were employed as heterogeneouscatalyst for the synthesis of polyhydroquinolinederivatives. All the polyhydroquinolinederivatives were characterized by Fourier transform infrared spectroscopy (FT‐IR) and Nuclear magnetic resonance spectroscopy (1H NMR). For the very first time ever we have used BiFeO3 as a recyclable magnetic nanocatalyst in the
通过自动燃烧合成了蔗糖螯合的铋铁氧体(BiFeO 3)纳米颗粒作为新型非均相催化剂。已采用不同的煅烧温度(150°C,450°C,550°C,650°C,750°C和850°C)获得单相BiFeO 3纳米粒子。钙钛矿结构的形成和有机相(蔗糖)的消失是通过傅立叶变换红外光谱(FT-IR)获得的。相的确定和结构表征是通过粉末X射线衍射(XRD)进行的。通过振动样品磁力计(VSM)分析了磁性,而表面积/孔体积是通过Brunauer-Emmett-Teller(BET)获得的。透射电子显微镜(TEM)分析了颗粒的大小和形态。通过热重分析(TGA)研究热稳定性,并通过X射线光电子能谱(XPS)确定组成元素。拉曼光谱证实了合成材料的钙钛矿结构。BiFeO 3如此获得的纳米颗粒用作合成多氢喹啉衍生物的非均相催化剂。所有聚氢喹啉衍生物均通过傅里叶变换红外光谱(FT-IR)和核磁共振光谱(1 H NMR)进
