Multiphasic bi-component TiO2–ZnO nanocomposite: synthesis, characterization and investigation of photocatalytic activity under different wavelengths of light irradiation

Resin-gel incorporation of high concentrations of W6+ and Zn2+ into TiO2-anatase crystal to form quaternary mixed-metal oxides: effect on the a lattice parameter and photodegradation efficiency

“…It was suggested that holes accumulated at the valence band of ZnO and electrons accumulated at the conduction band of TiO 2 so that migration could occur with minimal recombination. 31,[37][38][39] The abovementioned examples have focused on the formation of mixtures of metal oxides, where a great deal of research has been performed. On the contrary, less research has been focused on the synthesis and use of TiO 2 -based mixed metal oxides by introducing foreign metal ions into its crystal lattice structure for use in photocatalysis.…”

Bacteriostatic Activity of LLDPE Nanocomposite Embedded with Sol–Gel Synthesized TiO2/ZnO Coupled Oxides at Various Ratios

“…Further increment of light harvesting efficiency and antimicrobial efficacy could be attained through the formation of heterojunction between TiO 2 and ZnO. This improves the charge transport and enhances the charge carrier separation, in comparison to bare metal oxide [29,30,31]. Nevertheless, most studies are concerned only with nanoparticles [26,32,33,34], while studies related to antimicrobial efficacy of nanoparticle-embedded polymer matrix are scarce.…”

“…TiO2 can also be mixed / combined with different compounds, in multiphase systems as a route to achieving simultaneous multifunctional properties. For example, there are literature reports of TiO2 combined with ZnO, PbO, SnO2 or SiO2 where the presence of the additional phase led to higher photocatalytic activity and/or photoactivity using a visible light source [Rajbongshi, 2014;Bhachu, 2014;Chadwick, 2014;de Chiara, 2015].…”
