负载型金(Au)纳米催化剂对CO氧化反应过程具有较高的催化活性,而其负载载体的物化性质对Au催化活性的提升有显著影响。系统地总结了几种常见的Au催化剂载体(活性载体:TiO₂、CeO₂以及Co₃O₄;惰性载体:SiO₂和Al₂O₃)在协调Au催化氧化CO过程中的催化性能及相关的作用机制,重点分析了各载体对催化性能的影响,对负载型Au催化剂载体的选择及设计提供指导,并对未来Au催化剂的发展方向做了展望。

Supported gold (Au) nano-catalyst has high catalytic activity for CO oxidation reaction process,and the physical and chemical properties of the carrier used to support Au have a significant impact on the improvement of Au's catalytic activity.Several common carriers for supporting Au catalyst,including active carriers such as TiO₂,CeO₂ and Co₃O₄;inert carriers such as SiO₂ and Al₂O₃,are systematically summarized in terms of their catalytic performance and related mechanism in coordinating Au to catalyze the oxidation of CO.The influences of each carrier on the catalytic performance of the catalyst are emphatically analyzed,and the development direction of Au catalysts in the future is prospected.It provides guidance for the selection and design of carrier in supported Au catalyst,and gives prospects on the development directions of Au-based catalyst in the future.
