以磺酸功能化的二氧化硅为载体，负载金、铂、铱胶体，用于呋喃甲醛的还原胺化反应。采用77℃氮气物理吸附、X-射线衍射、H_2化学吸附和XPS等手段对催化剂进行了表征。结果表明，Ir、Au和Pt胶体均匀分散在SiO_2-SO_3载体上。XPS结果表明，磺酸基团与金属中心的相互作用有利于亚胺的形成和随后的加氢生成胺。
Gold, platinum and iridium colloids were supported on sulfonic acid-functionalized silica and were employed for the reductive amination of furfural. The catalysts were characterized by N2-physisorption at 77 K, X-ray diffraction, H2chemisorption and XPS. The results indicated that Ir, Au and Pt colloids were uniformly dispersed on the SiO2–SO3H support. XPS results showed the interaction of sulfonic acid groups and metal sites which favors the formation of imine and its subsequent hydrogenation to amine.
