自从发现金纳米颗粒对CO低温氧化具有惊人的高催化活性以来，人们一直在积极研究金在各种工业重要催化过程中的潜在用途。[1，2]值得注意的是，氧化物载体上的金纳米颗粒被认为是用于烃类选择氧化、二氧化碳加氢合成甲醇、水-气变换反应、氢还原一氧化氮、丙烯环氧化和CO优先氧化(Prox反应)的高活性催化剂。[3-8]许多氧化物，如二氧化钛，[9-21]Fe2O3，[1，22-24]Co3O4，[1、25、26]
Since the discovery of the surprisingly high catalytic activity possessed by gold nanoparticles for the oxidation of CO at low temperature, investigations into the potential uses of gold for various industrially important catalytic processes have been actively pursued.[1, 2] Notably, gold nanoparticles on oxide supports were regarded as highly active catalysts for the selective oxidation of hydrocarbons, methanol synthesis by hydrogenation of carbon dioxide, water–gas shift reaction, reduction of nitric oxide by hydrogen, propylene epoxidation, and preferential oxidation of CO (PROX reaction).[3–8] A number of oxides, such as TiO2,[9–21] Fe2O3,[1, 22–24] Co3O4,[1, 25, 26]
