techniques like BET, TEM, ICP-OES, FTIR, EDS, MAP, SEM, XRD, TGA/DTG, and VSM. Finally, the catalytic efficiency of the novel synthesized nanocatalyst was scrutinized in the synthesis of bis (pyrazolyl)methane derivatives. Furthermore, the recyclability and stability of Fe3O4@THAM-Pd MNPs were checked. The results showed that Fe3O4@THAM-Pd MNPs can use as a new and efficient heterogeneous catalyst. The
在这项研究中,报道了另一种开发包括Pd纳米颗粒在内的纳米材料的方法。通过自下而上的策略合成了Fe 3 O 4 @ THAM-Pd MNP。然后,通过多种技术如BET,TEM,ICP-OES,FTIR,EDS,MAP,SEM,XRD,TGA / DTG和VSM完全确认了纳米催化剂的结构。最后,在双(吡唑基)甲烷衍生物的合成中仔细研究了新型合成纳米催化剂的催化效率。此外,检查了Fe 3 O 4 @ THAM-Pd MNP的可回收性和稳定性。结果表明,Fe 3 O 4THAM-Pd MNP可用作新型高效的多相催化剂。纳米催化剂的稳定性可能归因于富N的壳层与Pd纳米颗粒之间的强相互作用。
