| 摘要: | 利用淀粉样蛋白纤维为生物模板合成了尺寸均匀且分散性较好的金属钯纳米颗粒. 原子力显微镜的测试表明, 钯纳米颗粒的平均粒径大小为(12.8±0.5)nm. 利用X射线光电子能谱对钯纳米颗粒/胰岛素进行化学组分表征, 最后将钯纳米颗粒/胰岛素催化剂应用于Suzuki交叉偶联催化反应以及过氧化氢的检测. 实验结果表明, 生物模板制备的钯纳米颗粒催化剂具有高效的催化性能, 可用于多种铃木交叉偶联反应, 并能很好地检测低浓度的过氧化氢溶液. |
| Abstract: | In this paper, we present a green and facile approach to synthesize the uniformly dispersed Pd NPs using amyloid fibrils as bio-templates. Firstly, 1 mg?mL-1 insulin peptides are incubated at 80℃for 3 days to form protein fibrils, then insulin fibrils are mixed with palladium chloride aged for several days at room temperature to achieve uniformly dispersed Pd NPs. The diameter of Pd NPs is identified to be about (12.8±0.5) nm according to AFM measurements. The chemical compositions of Pd/insulin are characterized by X-ray photoelectron spectroscopy. Finally, the Pd NPs catalysts are applied to Suzuki coupling reaction and hydrogen peroxide detection, indicating the satisfying ability to detect the low-density hydrogen peroxide solution. |
