used as a heterogeneous catalyst in C–H bond activation and the electrooxidation of ethanol. The study demonstrated α-Syn-PdNPs to be a superior heterogeneous catalyst for the synthesis of pharmaceutically valuable benzofuran, naphthofuran, coumarin and N-arylindole via C–H activation. Further, the electrooxidation of ethanol using α-Syn-PdNPs displayed an electrochemically active surface area of 160.6
淀粉样蛋白是高度有序的纳米原纤维,其抗张强度与钢相似,因此可以抵抗极端的pH和温度。基于此原理,我们证明了以α-突触核蛋白(α-Syn)原纤维为模板,可以轻松合成钯,铜,铂,金和银纳米复合材料。我们表明,α-Syn-原纤维-钯纳米颗粒(α-Syn-PdNPs)复合材料可以用作C–H键活化和乙醇电氧化的非均相催化剂。研究表明,α-Syn-PdNPs是一种优异的非均相催化剂,可通过以下方法合成药学上有价值的苯并呋喃,萘并呋喃,香豆素和N-芳基吲哚。C–H激活。此外,使用α-Syn-PdNPs对乙醇进行的电氧化表现出160.6 m 2 g -1的电化学活性表面积,该表面积比先前报道的负载Pd纳米复合材料的值高得多。
