Co3O4/GO/PMS体系对NOx催化氧化的研究
Environmental Science & Technology(2014)
Abstract
文章通过对GO、Co3O4以及Co3O/GO的XRD、FT-IR以及拉曼光谱图的分析研究表明GO上已成功负载Co3O4,在此基础上考察了pH、PMS浓度、Co3O4/GO浓度、反应时间、温度等因素对Co3O4/GO/PMS催化氧化NOx的影响,结果表明:pH为4.0、PMS浓度为6 mmol/L、CoO4/GO浓度为0.75 mmol/L、反应时间为60min,反应温度为35℃的情况下,对NOx氧化率可以达到69.3%.催化剂简单易制,工艺简单,物耗低.
