摘要
石墨烯由于其特殊的电学、热学、力学、光学等性质以及在纳米电子器件、储能材料、光电材料等方面的潜在应用,引起了科学界新一轮的"碳"热潮。铁酸盐具有特殊的物理结构和化学性质,一般带隙较窄,能够接受太阳光甚至可见光,受激发产生电子空穴对氧化分解有机污染物,目前在光催化降解有机污染物领域得到广泛应用。该文综述了近年来国内外关于石墨烯掺杂铁酸盐光催化剂的最新研究进展,重点包括该材料的各种制备技术,该材料在光降解有机污染物方面的应用,并展望了其未来发展趋势和研究重点。
Graphene caused a new round of 'carbon'boom in the scientific community,due to its exceptional properties including electricity,thermology,mechanics,photology and the potential application fields ranging from the nano-electronic devices,energy storagematerials,photoelectric materials.Ferrites have special physical structure and chemical properties,a narrow band gapthey possessed make them capable of absorbing sunlight,even visible light,which are excited to create e^-/h^+pairs that play an important role in the oxidation and decomposition of organic contaminants,which has been widely used in the field of photodegradation of organic pollutants.The article reviews the latest research progresses about graphene doping ferrite photocatalyst in the domestic and overseas,highligts the various preparation techniques,addresses the applications in the photodegradation of organic contaminants.The review also indicates some vital problems and the future development trends of the Ferrites/graphene photocatalyst.
