聚合物包埋的、碳稳定的金纳米团簇在水介质中以分子氧为氧化剂的多相催化仲醇氧化反应中具有很高的活性。通过对催化剂制备方法的优化，得到了高负载量、高效率的催化剂，并能在温和的条件下对多种仲醇进行氧化。催化剂可以回收和重复使用几次，而不会有明显的活性损失。此外，还研究了(+/-)-1-苯乙醇的氧化反应动力学。
Polymer-incarcerated, carbon-stabilized gold nanoclusters were found to be highly active in heterogeneous catalysis for the oxidation of secondary alcohols using molecular oxygen in aqueous medium. After optimization of catalyst preparation methods, highly loaded and highly effective catalysts were obtained, and a broad range of secondary alcohols could be oxidized by using these catalysts under mild conditions. The catalysts could be recovered and reused several times without significant loss of activity. Moreover, kinetics of the oxidation reaction with (+/-)-1-phenylethanol was investigated.
