| 摘要: |
| 采用溶胶-凝胶法和超临界干燥法制备了Cu/SiO2和Co/SiO2 气凝胶催化剂, 对其结构和形貌进行了XRD、TEM 和比表面分析, 并考察了其对CO 氧化的催化性能。实验结果表明, 制得的Cu/SiO2 和Co/SiO2 气凝胶催化剂均保留了气凝胶的纳米网络和高比表面积, 活性组份均匀地分散在纳米级二氧化硅气凝胶载体中, 对CO的氧化均表现出高的催化活性。 |

| Abstract: |
| M-SiO2 aerogels catalysts(M=Cu or Co)are prepared by sol-gel process and supercritical drying. The resulting aerogels are characterized using transmission electron microscopy (TEM), XRD and nitrogen adsorption analysis. Their catalytic behavior for CO oxidation has been studied. The results indicate that Cu-SiO2 or Co-SiO2 catalysts have high catalytic activity at 100-400℃. |
