摘要
最近几年,由于石油化工、焦化、塑料等众多工业的行当高速的发展,工业废水排放也随之增多,各类高纯度的碳水化合物和蛋白质以及脂肪等有机污染物直接排放到水中,导致越来越多的水资源遭到污染。针对此情况,碳基光催化剂的治理水污染优势得到了很好地利用,相关研究成果也是得到进一步的进展。碳基光催化材料结构性能多样,研究它具有一定的科学理论价值。作为碳基光催化材料,石墨烯复合物光催化剂具有石墨烯特有的电子传输特点,进而改善石墨烯复合物光催化剂的导电性。石墨烯具有大的比表面积,使其负载光催化剂更具优势。石墨烯复合物使石墨烯通过掺杂进行化学改性使纳米带的能隙变大,从而达到一个增强复合物的物理化学性能。而且它的的制备方法操作简单,可以为类似的石墨烯复合物材料和氧化亚铜/活性炭光催化材料的制备提供借鉴和参考,具有实际意义。
In recent years,because of the rapid development of many industries,such as petrochemical,coking,plastic,and so on,the discharge of industrial waste water has also increased. All kinds of high purity organic pollutants such as carbohydrates,proteins and fat are discharged directly to the water,causing more and more water sources to be polluted. For this reason,the advantages of carbon based photocatalyst for water pollution control have been well utilized,and the related research achievements have been further developed. Carbon based photocatalytic materials have various structures and properties,so it has certain scientific and theoretical value. As a carbon based photocatalyst,graphene composite photocatalyst has the characteristic of electronic transmission of graphene,and then improves the conductivity of the graphene complex photocatalyst. Graphene has large specific surface area,which makes the photocatalyst more advantageous. Graphene composite enables graphene to be chemically modified by doping to increase the energy gap of nanobelts,thereby achieving an enhanced physical and chemical properties of the composite. It is of practical significance to provide reference and reference for the preparation of similar graphene composite materials and the preparation of copper oxide/activated carbon photocatalyst.
