Environmental pollution, especially water pollution, has become a serious problem worldwide. Therefore, a number of methods have been investigated and applied to deal with this problem. Using novel materials for environmental treatment is one of the most popular approaches. Among them, graphene oxide (GO) and GO-based materials have attracted much attention due to their unique properties. GO-based materials are able to adsorb various types of contaminants onto their high specific surface areas with the addition of various multifunctional groups. Besides, GO-based materials express both catalyst activity for the degradation of pollutants and antibacterial properties. To synthesize GO-based materials, other components (polymers, metals and metal oxides) are usually combined onto the surface of previously prepared GO. This paper reviews and discusses the synthesis of GO-based materials and their use in treating contaminated water.
