摘要
文章通过对GO、Co3O4以及Co3O4/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NO X的影响,结果表明:pH为4.0、PMS浓度为6 mmol/L、Co3O4/GO浓度为0.75 mmol/L、反应时间为60 min,反应温度为35℃的情况下,对NO X氧化率可以达到69.3%。催化剂简单易制,工艺简单,物耗低。
Through XRD, FF-IR and Raman spectra analysis of GO, Co3O4 and Co3O4/GO, the result shows that Co3O4 was distributed on GO, and effects of pH, PMS concentration, Co3O4/GO concentration, reaction time and temperature on Co3O4/GO/PMS catalytic oxidation NOx were investigated. Results indicated that NOx oxidation rate can reach 69.3% under the conditions of pH 4.0, PMS concentration 6 mmol/L, Co3O4/GO concentration 0.75 mmol/L and reaction temperature 35 ℃ for 60 min. The catalyst is easy to prepare, with simple process and low material consumptions.
