“…In this method, TiO 2 was laminated on the GO sheets followed by crystallization into anatase nanocrystals via hydrothermal treatment. Guo et al (2013) prepared the hybrid films of TiO 2 and graphene with the sol-gel technique via the collaborated approach of heat treatment. This hybrid films were coated on 304-stainless steel to provide photocathodic shield.…”

Technologies for wastewater remediation have been growing ever since the environmental and health concern is realized. Development of nanomaterials has enabled mankind to have different methods to treat the various kinds of inorganic and organic pollutants present in wastewater from many resources.Among the many materials, semiconductor materials have found many environmental applications due to their outstanding photocatalytic activities. TiO 2 and ZnO are more effectively used as photocatalyst or adsorbents in the withdrawal of inorganic as well as organic wastes from the wastewater. On the other hand, graphene is tremendously being investigated for applications in environmental remediation in view of the superior physical, optical, thermal, and electronic properties of graphene nanocomposites. In this work, graphene-TiO 2 and graphene-ZnO nanocomposites have been reviewed for photocatalytic wastewater treatment. The various preparation techniques of these nanocomposites have been discussed. Also, different design strategies for graphene-based photocatalyst have been revealed. These nanocomposites exhibit promising applications in most of the water purification processes which are reviewed in this work. Along with this, the development of these nanocomposites using biomass-derived graphene has also been introduced. Practitioner Points• Graphene-TiO 2 and graphene-ZnO nanocomposites are effective for wastewater treatment through photocatalysis.• These nanocomposite photocatalysts have been used in the form of membrane as well as antibacterial agents.• Synthetic strategies and design considerations of graphene-based photocatalyst play a major role.• Biomass-derived graphene-TiO 2 and graphene-ZnO nanocomposites have also found application in wastewater treatment.

“…26 Previously, graphene has been mostly explored in the physical eld for application in photovoltaic devices, photocatalysis and sensors because their surfaces are chemically inert. [27][28][29] Recently, the possible applications of graphene-based materials have rapidly expanded to other areas such as environmental remediation. 30 For molecular separation processes, computational simulation predicts that graphene-based membrane demonstrates a great potential for molecular separation.…”

“…More specifically, constructing heterojunctions by combining with other materials has proven to be a valid method for improving the photoelectrochemical properties of TiO 2 . The materials used for this strategy include metal oxides (In 2 O 3 [22], MoO 3 [23], Bi 2 O 3 [24], WO 3 [25,26], RuO 2 [27,28]), metal sulfides and selenides (Ag 2 S [29], Bi 2 S 3 [30], Ag 2 Se [31]), graphene [32][33][34], Co(OH) 2 [35], and ZnFeAl-layered double hydroxides [36].…”

TiO2 is an attractive semiconductor suitable for photocathodic protection, but its weak absorption of visible light and low quantum yield limit its usage. Here, a new heterostructured SnIn4S8 nanosheet/TiO2 nanotube photoanode was prepared and its photocathodic protection performance was analyzed. SnIn4S8 nanosheets were uniformly deposited on the surface of the TiO2 nanotube via a solvothermal treatment. The SnIn4S8/TiO2 composite exhibited better photocathodic protection performance compared with pure TiO2 nanotubes, owing to its good visible-light response and photogenerated carrier separation efficiency. Moreover, the composite exhibited a maximum photocurrent density of 100 μA cm−2 for a 6 h solvothermal reaction under visible light irradiation. The negative shift of the photoinduced potential of Q235 carbon steel connected to the composite could reach 0.45 V versus SCE. Therefore, the SnIn4S8/TiO2 composite can offer efficient photocathodic protection for Q235 carbon steel against corrosion in 3.5 wt% NaCl solution. This work provides a new approach for the development of high-efficient photoanode materials for the photocathodic protection of metals.
