We introduce a new example of the in situ preparation and fabrication of stable gold nanoparticles on silica in an aqueous medium, by using only lipid-grafted silica particles in HAuCl(4) solution without addition of any external reducing agent. The lipid-grafted silica particles have been synthesized by graft-to methodology and characterized by elemental analysis, thermogravimetric analysis and Fourier-transform infrared spectroscopy. The metamaterial particles show high catalytic activity for the reduction of p-nitrophenol to p-aminophenol.
我们介绍了一个新的实例，即在水相介质中，通过仅使用接枝有脂质的硅胶颗粒在 HAuCl4 溶液中，无需添加任何外部还原剂，原位制备和制造稳定的金纳米粒子。接枝有脂质的硅胶颗粒是通过接枝法合成的，并通过元素分析、热重分析和傅里叶变换红外光谱进行了表征。金属材料颗粒对 p-硝基苯酚还原为对氨基酚表现出很高的催化活性。
