The TiO2 and CdS nanoparticles were synthesized using sol gel method. TiO2 -CdS nanocomposite was synthesized by ultra-sonication method. The SEM image reveals the spherical shaped pure TiO2 and pure CdS nanoparticle and was uniformly mixed in the TiO2 -CdS nanocomposite. The photocatalytic result reveals that MB dye removal was observed to be higher in the TiO2 -CdS nanocomposite as compared with pure TiO2 nanoparticle for 90 minutes of visible light irradiation.

“…In this context, graphene and its derivatives, such as graphene oxide (GO) and reduced graphene oxide (rGO), find attractive applications in electronic and optoelectronic devices, energy storage devices, chemical sensors and biomedical implants [141][142][143]. Moreover, a graphene sheet with a lateral dimension of several micrometers can serve as a template for anchoring TiO 2 NPs onto its surface [102,[144][145][146].…”

This article provides an overview of current research into the development, synthesis, photocatalytic bacterial activity, biocompatibility and cytotoxic properties of various visible-light active titanium dioxide (TiO2) nanoparticles (NPs) and their nanocomposites. To achieve antibacterial inactivation under visible light, TiO2 NPs are doped with metal and non-metal elements, modified with carbonaceous nanomaterials, and coupled with other metal oxide semiconductors. Transition metals introduce a localized d-electron state just below the conduction band of TiO2 NPs, thereby narrowing the bandgap and causing a red shift of the optical absorption edge into the visible region. Silver nanoparticles of doped TiO2 NPs experience surface plasmon resonance under visible light excitation, leading to the injection of hot electrons into the conduction band of TiO2 NPs to generate reactive oxygen species (ROS) for bacterial killing. The modification of TiO2 NPs with carbon nanotubes and graphene sheets also achieve the efficient creation of ROS under visible light irradiation. Furthermore, titanium-based alloy implants in orthopedics with enhanced antibacterial activity and biocompatibility can be achieved by forming a surface layer of Ag-doped titania nanotubes. By incorporating TiO2 NPs and Cu-doped TiO2 NPs into chitosan or the textile matrix, the resulting polymer nanocomposites exhibit excellent antimicrobial properties that can have applications as fruit/food wrapping films, self-cleaning fabrics, medical scaffolds and wound dressings. Considering the possible use of visible-light active TiO2 nanomaterials for various applications, their toxicity impact on the environment and public health is also addressed.
