Preparation of Gold Nanoparticles Supported on Nanocellulose and Catalytic Performance
摘要
Abstract
Dialdehyde nanocellulose (DNC) was prepared using sodium periodate as an oxidant from nanocellulose (NC). Gold nanoparticles/NC catalyst was further synthesized by using DNC as reducing agent and template. The preparation conditions, chemical structure and crystal structure of catalysis was characterized by UV-vis (ultraviolet visible) spectra, FT-IR (Fourier transform infrared) spectra and XRD (power X-ray diffraction). In addition, the oxidation state and size of gold nanoparticles on the surface of cellulosic carrier was determined by XPS and TEM (transmission electron microscopy). The catalytic performance of the synthesized catalysis was investigated by the reduction of 4-nitropheol with sodium borohydride as a model reaction. It was found that the conversion ratio could be up to 94% after reacting for 55 min, and the catalytic rate constant of catalysis in the reaction was calculated to be 0.073 min-1.关键词
