中文摘要: 石墨烯基材料由于其非金属毒性和抗二次污染性被广泛应用.采用改良Hummers法制备氧化石墨，并加入尿素进一步制备出掺氮石墨烯，用以催化单过氧硫酸氢钾（PMS）产生硫酸根自由基氧化降解酸性橙Ⅱ废水，同时考察了掺氮量、pH值等因素对降解性能的影响.结果表明，掺氮石墨烯具有高效催化活性，完全降解酸性橙Ⅱ仅用55 min.
Abstract:Graphene-based materials,as excellent catalysts,are widely used due to the metal-free nature of graphene which can completely prevent toxic metal leaching and the associated secondary contamination.Here,graphite oxide is obtained via modified Hummers,and is further applied to the preparation of nitrogen-doped graphene,which can efficiently activate peroxymonosulfate (PMS) to produce sulfate radicals to oxidize Orange Ⅱ solution. Nitrogen content,pH value as influencing factors of degradation effect are investigated.The results show that nitrogen-doped graphene with a high catalytic activity and Orange Ⅱ can be completely degraded within 55 min.
keywords: sulfate radicals N-Graphene orange Ⅱ
