| 摘 要： | 制备了一系列负载型纳米Au/Cr_2O_3催化剂,采用ICP、FTIR、XRD和N2吸附脱附对所制备的催化剂进行了表征.以3%的H_2O_2为氧化剂,考察其对甘油选择性氧化反应的催化性能.结果表明,该类催化剂在甘油选择性氧化反应中表现出了较好的催化性能,其中Au/Cr_2O_3(0.95%)的催化性能最好,甘油转化率可达81.5%,甘油酸选择性为67.0%,且该非均相催化剂重复使用10次后仍保持较高的催化活性.

| Abstract: | A series of supported nanosized Au/Cr2O3 were prepared and characterized by various physico-chemical measurements such as ICP, FTIR, XRD and N2 sorption. The supported catalysts were effective in the selective oxidation of glycerol to glyceric acid with 3% hydrogen peroxide. Under the optimal reaction conditions, the highest conversion of glycerol reached 81.5% with 67.0% of the selectivity to glyceric acid over Au/Cr2O3(0.95%). In addition, the catalytic activity was remained after being recycled 10 times. |
