离子液体中纳米金催化剂的制备及其催化活性
Preparation of gold nanoparticles catalyst in ionic liquid and its catalytic activity
摘要
Abstract
Nanocomposite Au/SiO2 catalyst was synthetized by one-step sol-gel method in the ionic liquid [C6mim] PF6 with HAuCl4 as the gold source and hydrazine hydrate as the reducing agent. Synthetic products were characterized by means of XRD,TEM,N2 adsorption and other representation methods. The characterization results showed that Au nanoparticles which loaded SiO2 had spherical appearance, uniform size and good dispersion, of which the diameter of Au nanoparticles was about 2-3 nm.In the reaction of methane oxidation,when made composite nano Au/SiO2 as catalyst, the highest methane conversion rate reached 24. 9%.关键词
