废触媒制备活性炭负载氧化锌的结构及其空气净化性能

The Structure of ZnO/AC Prepared from Spent Catalyst and Its Purification Properties for Air

利用负载醋酸锌的废触媒为原料,用微波处理制成活性炭负载氧化锌的复合材料。研究了复合材料对甲醛和TVOC气体的降解性能,运用现代分析仪器表征了材料的微观结构和表面特性,结果表明:该复合材料具有发达的孔隙结构,对空气中的有机挥发物有较高吸附容量,负载的氧化锌呈六方结构,对甲醛具有催化降解作用。

The composite material,supported ZnO/ activated carbon,were prepared from spent catalyst supported zinc acetate by microwave heating.The adsorption and catalytic property of the material have been studied for formaldehyde and TVOC,and the microscopic structural and surface properties of the material were analyzed by modern analysis instruments.The results show that the composite material has developed pore structure and then higher adsorption capacity for the volatile organic compounds in air,and the supported zinc oxide to be submit 6 square structures has higher catalytic property for the formaldehyde in air.
