We have presented the green synthesis and characterization of nano-titania (TiO2 NPs) by using Eucalyptus globulus leaf aqueous extract in a greener approach leading to their utilization as a catalyst in one-pot, three-component A3 coupling reactions. The composition of the as-prepared TiO2 NPs were confirmed by various analytical and spectroscopic techniques such as powder X-ray diffraction, scanning
我们展示了纳米二氧化钛 (TiO 2 NPs)的绿色合成和表征,通过以更环保的方式使用蓝桉叶水提取物,从而将其用作一锅三组分 A 3偶联反应的催化剂。通过各种分析和光谱技术,如粉末 X 射线衍射、扫描电子显微镜、透射电子显微镜、傅里叶变换红外光谱、热重分析、动态光散射分析和比表面积确认了所制备的 TiO 2 NPs的组成。通过Brunauer-Emmett-Teller分析测量。二氧化钛2 NPs 表现出平均粒径为 12 nm 的纯锐钛矿相结构。
