Graphene is an interesting two-dimensional carbon sheet possessing single-layered atom thickness that confers unique physical and chemical properties. The pristine graphene sheets have some limited applications in water purification, but the modification of graphene into the graphene composite by the incorporation of some functional groups or nanoparticles on the surface extensively increases its environmental applications. Recently, graphene nanocomposites have found to show very promising applications in all types of water purification. The present review highlights the recent developments in the applications of graphene and graphene-based composites as adsorbent, catalyst, photocatalyst, electrocatalyst, photoelectrocatalyst, and disinfection and desalination agent in comprehensive water purification systems. We primarily focus on the environmental engineering applications of graphene nanocomposites as sorbent materials for the elimination of toxic inorganic (cationic and anionic), organic, and mixed/multiple pollutants, and as catalysts for the degradation of toxic organic contaminants using catalytic oxidation, photocatalytic oxidation, electrocatalytic oxidation, and photoelectrocatalytic oxidation. We have also discussed the use and feasibility of graphene nanocomposites in water disinfection and desalination. Finally, the future challenges and perspectives are discussed.

Recently, there is crucial interest in the design and fabrication of nanocatalysts for efficient decomposition of organic pollutants in wastewater using visible light. This work reports the assembling fabrication of synergetic photocatalytic Au/TiO2/RGO nanostructures by utilizing the reduced graphene oxide (RGO) as substrate material and efficient separator for electrons and holes. The Au/TiO2 nanostructures with a ≈7 nm TiO2 particles size are dispersed uniformly on RGO nanosheets. UV–vis diffuse reflectance spectroscopy verifies that Au/TiO2/RGO nanocomposites show strong absorption of visible light. The degradation efficiency after 1 h for hydroquinone under visible light and UV light is ≈77% and ≈90%, respectively. Under visible light, the calculated apparent rates (k) of the Au/TiO2/RGO nanocomposites are 0.0112 and 0.0174 min−1 for decomposition of methylene blue and hydroquinone. That are five times greater than that of bare TiO2. The high photocatalytic activity is mainly attributed to the synergy between RGO and Au/TiO2 nanostructure. The strategy of composite nanostructures assembling on RGO is ensured to have a great practicable potential for the designing of high efficient multielement composite nanoparticles catalysts.

“…Another merit of using titanium mesh as electrode substrate is that the internal stress inside the anodic TiO 2 nanotubes grown on cylindrical mesh wires is lower than that of the nanotubes grown on traditional titanium foils. As a consequence, the physical stability of the TiO 2 nanotubes grown on titanium mesh is stronger …”

Photocatalysis and photoelectrocatalysis are highly promising for applications in the energy and environment sectors. Several photocatalytic devices based on TiO2 nanotubes grown on two‐dimensional (2D) substrate (such as titanium foil) have been developed, but there has been little research on three‐dimensional (3D) TiO2 nanotubes which are expected to offer significantly enlarged surface area and much improved photocatalytic efficiency. Here, a method of building 3D TiO2 nanotube arrays (3D‐TNTAs) on titanium mesh by anodization via controlling the reaction time and electrolyte is reported. It is found that the electrochemically active area of such a titanium mesh is almost 4 times larger than that of the traditional titanium foil. Moreover, through making composites of graphene oxide and ZnxCdyS onto 3D TiO2 nanotubes, hierarchical nanotube arrays (ZnxCdyS/GO/3D‐TNTAs) are made by calcination‐deposition of graphene oxide followed by a facile successive ionic layer adsorption reaction (SILAR) treatment with ZnxCdyS. Characterization of the ZnxCdyS/GO/3D‐TNTAs indicates that this hierarchical multi‐layered nanostructure has a much improved photoelectrochemical property due to the enlarged surface area and improved electron–hole separation capability, demonstrating the great potential for applications in photoelectrocatalytic devices for environmental technologies.
