| 摘 要： | 利用共沉淀法（CP）和沉积-沉淀法（DP）制备了Au／C0304催化剂，考察了制备条件及不同制备方法对金粒子大小的影响。结果表明，负载量为1wt％Au／Co3O4金粒子最小，分散度最好，而焙烧温度太高不利于金粒子的分散，另外，DP法制备的金粒子比CP法制备的要小。

| Abstract: | Au/Co_3O_4 catalyst was prepared by co-precipitation(CP) and deposition-precipitation(DP).And effects of preparation conditions and methods on the particle size were discussed.It was found that the gold particle was small when loading of gold was low and higher calcination temperature was not good to the dispersion of supported gold.The gold particle size on the catalyst prepared by DP was smaller than that prepared by CP. |
