研究了在气-液-液-固流动体系中一次通过时催化醇类有氧氧化的Au-Pt和Au-Pd双金属纳米团簇。在苯三氟化苯(BTF)/水介质中，醇类通过Au-Pt催化剂转化为醛类和酮类；在甲醇/水介质中，通过Au-Pd催化剂转化为相应的甲酯类。流动体系在产率和选择性上都优于间歇体系。
Au-Pt and Au-Pd bimetallic nanoclusters that catalyzed the aerobic oxidation of alcohols during a once-through pass through gas-liquid-liquid-solid flow systems were developed. Alcohols were converted to aldehydes and ketones in benzotrifluoride (BTF)/water media by Au-Pt catalyst or to the corresponding methyl esters in methanol/water media by Au-Pd catalyst. The flow systems were superior to the batch systems in terms of both yield and selectivity.
