以氧化石墨烯(GO)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负载型催化剂复合物——Co3O4/GO,采用XRD、FT-IR、Raman、EDS和SEM表征测试,并考察了无机盐离子(Cl-、HCO-3、H2PO-4和NO-3)对催化降解PVA的影响。结果表明,Co3O4已成功负载到GO上;负载型催化剂Co3O4/GO具有很高的催化活性;不同无机盐离子对催化降解反应的影响不同。本研究内容将对实际PVA废水处理过程起到借鉴和指导作用。
The supported catalyst complex Co3O4 / GO, which was applied to advanced oxidation based on sulfate radical, was prepared by using graphene oxide (GO) as the carrier of Co3O4. XRD, FT-IR, Raman, EDS and SEM The effects of inorganic salts (Cl-, HCO-3, H2PO-4 and NO-3) on the catalytic degradation of PVA were investigated. The results show that Co3O4 has been successfully loaded onto GO. The supported catalyst Co3O4 / GO has high catalytic activity. Different inorganic ions have different effects on the catalytic degradation. The content of this study will play a guiding role in the actual PVA wastewater treatment process.
