with average sizes ranging from 53 to 60 nm measured by DLS technique. Next, the catalytic activity of pure and Al-doped ZnO nanopowders was investigated in terms of synthesis of 3,4,5-substituted furan-2(5H)-one derivatives using the three-component reaction of aldehydes, aromatic amines, and acetylenic esters. This procedure has advantages such as high yields, simple methodology, and easy work-up
铝掺杂的ZnO纳米结构是通过简单的沉淀方法制备的,并通过多种技术进行了表征,包括XRD,TEM,EDX,UV-Vis和DLS。所有XRD图谱均显示了纯铝掺杂的ZnO纳米粉体中没有杂质的六方单相结构。样品由通过DLS技术测得的平均粒径为53至60 nm的颗粒组成。接下来,利用醛,芳族胺和三价胺的三组分反应,通过合成3,4,5-取代的呋喃-2(5 H)-one衍生物,研究了纯铝掺杂的ZnO纳米粉的催化活性。炔属酯。该过程具有诸如高产量,简单的方法和容易的后处理的优点。
