摘要 以膨胀石墨(EG)作为Co3O4的载体,制备出应用于基于硫酸根自由基的高级氧化技术的非均相催化剂复合物——Co3O4/EG,并用其降解水中的偶氮染料酸性橙Ⅱ,同时考察了氧化剂投加量、催化剂投加量、温度等因素对降解性能的影响以及催化剂的稳定性。结果表明,Co3O4/EG具有很高的催化活性,在最佳条件下能在8min内完全降解酸性橙Ⅱ,且具有很好的稳定性。 A heterogeneous catalyst compound, Co3O4/EG, which apply in advanced oxidation technologies based on the sulfate radicals,was prepared using expanded graphite as the supporter of Co3O4. The obtained catalyst compound was used in degradation of azo-dye （acid orange II ） in solution. Several operational parameters, such as catalyst amount,oxidant amount and temperature on degradation efficiency was investigated and the stability of catalyst were also analyzed. The results showed that Co3O4/EG had perfect catalytic activity and stablity;it could completely removed acid orange II within 8 min in the optimum conditions.
