紫外光预处理对三维Co/rGO催化剂甲醛催化氧化性能影响的研究

Light-Enhanced HCHO Catalytic Oxidation on Three-dimensional Co/rGO Catalyst

甲醛是我国室内环境最为普遍的挥发性有机污染物(VOCs),严重危害人体健康。催化氧化技术具有运行温度低、无二次污染等优势,成为目前甲醛净化最具有前景的方法。但是,催化剂具有成本较高、降解效率低和机理不明等问题,本工作利用较为简单的水热法一步制备出了具有三维结构的rGO和Co/rGO催化剂,重点研究紫外光预处理对三维CoOx/还原氧化石墨烯催化剂(Co/rGO)催化氧化甲醛性能的影响,并探究其相应的机理。

Formaldehyde(HCHO)is regarded as one of major and common indoor pollutants,and has serious adverse influences on human health.Catalytic oxidation method is considered as a promising technique for HCHO removal among the various treatment methods,because of its energy saving,high efficiency and environmental friend.Herein,we prepare the 3Dreduced graphene oxide(rGO)and composite of cobalt oxide and reduced graphene oxide(Co/rGO)by a one-step hydrothermal method in order to investigate the effect of Uv light treatment on the HCHO catalytic behavior.
