In this study, graphitic carbon nitride g-C3N4 was used to create composites with NiTiO3 by thermal polymerization method to improve their photocatalytic activity. In this process, the formation of g-C3N4 was generated from various precursors: dicyandiamide, melamine, urea or thiourea. Due to the nature of precursors, the g-C3N4/NiTiO3 composites express very different performance, from the polymerization reaction process to the physical and chemical properties. These materials were studied deeply of their functional groups on the g-C3N4 molecules, the role of these functional groups on the interaction between g-C3N4 and NiTiO3, on the properties of composites and on the photocatalytic activity. These materials have a high potential to apply in photocatalysis areas, such as photodegradation of organic contaminants, water splitting, etc. |
