摘要
采用固定化凝胶法制备1%Au/C催化剂。对Au/C催化剂的寿命进行了测试,结果显示:经过9次重复使用,每次3 h,Au/C催化剂的活性下降.同时比较了制备的Au/C和商业Pd/C催化剂对葡萄糖的液相催化氧化反应,证明Au/C催化剂明显优于Pd/C催化剂.
1% Gold on carbon was prepared by immobilizing gold sol. A test on the lifetime of the catalysts was carryed through. It showed Au/C catalyst activity declined, after nine runs Recycling use, each three hours. At the same time a comparison of the Au/C and commercial Pd/C catalyst for the liquid - phase catalytic oxidation of glucose reaction, that proved Au / C catalyst was superior Pd/C catalyst.
