Over the past few decades, heterogeneous photocatalysis has become a "green " alternative to traditional methods to degrade various environmental pollutants. TiO2, a low-cost and ultraviolet-light-active photocatalyst has been intensively used to decompose organic pollutants in water. The combination of TiO2 with non-toxic carbonaceous nanomaterials (CNMs) has been proved to extend TiO2 light absorption from ultraviolet (UV) to visible or even near infrared light region. Over the last decade, numerous studies on the development of CNM/TiO2 heterojunctions as efficient visible-light-responsive photocatalysts have been reported. However, a comprehensive review with respect to their synthesis, structural characteristics, photocatalytic activity enhancement is absent. In this review, the construction and characteristics (e.g. band structures, optical absorption, and interfacial charge transfer) of each class of CNM/TiO2 heterojunctions will be comprehensively reviewed. In addition, the application of CNM/TiO2 heterojunctions for photocatalytic degradation of persistent organic pollutants will be presented in detail. This review ends with a summary and future perspectives in exploring high performance CNM/TiO2 photocatalysts.
