光谱表征金纳米粒子的制备及催化性能
Study on Preparation and Catalysis Property of Au Nanoparticles by Spectroscopic Characterization
采用原位还原法合成不同粒径的金纳米粒子，利用透射电子显微镜和X-射线衍射对金纳米粒子进行相关表征。X-射线衍射研究发现金纳米粒子出现位于38.18°的特征峰，由此可推测金纳米粒子的粒径小于10 nm，结果与透射电子显微镜结果一致。将此金纳米粒子体系催化对硝基苯酚制备对氨基苯酚，紫外-可见吸收光谱和荧光光谱表征结果证实了良好的催化活性。
he Au nanoparticles were located evenly onto surfaces of the PNIPAAm-g-PAN/PSt microspheres, which were prepared by in situ reduction of Au3+. The properties of Au nanoparticles located polymeric microspheres were studied by TEM and XRD. According to 38.18° characteristic peak of XRD，It was found that the size of Au nanoparticles could be controlled above 10 nm, which accorded with TEM. The Au nanoparticles have very high catalytic activity in catalysis reduction of p-nitrophenol based on the results of UV-vis and Fluorescence spectroscopy.
