Synthesis of titanate/anatase composites with highly photocatalytic decolorization of dye under visible light irradiation

Influence of fluorine on the structure and photocatalytic activity of TiO2 film prepared in tungstate-electrolyte via micro-arc oxidation

“…TiO 2 has been proven to be an effective material for photocatalytic degradation of aquatic organic pollutants [1][2][3]. However, photocatalytic activity of pure TiO 2 is limited by easy recombination between photo-induced electrons and holes.…”

“…To improve photocatalytic activity of TiO 2 for practical application, several approaches have been developed, including doping techniques, semiconductors coupling and nanosized process for enhancing the specific surface area of catalysts [4,5]. Among these, coupling other semiconductor with TiO 2 such as WO 3 [6], CdS [7], ZnS [8], is a promising way to enhance photocatalytic activity by promoting the charge separation and extending wavelength for photoexcitation.…”

Synthesis of ZnO/titanate nanocomposites with highly photocatalytic activity under visible light irradiation

“…The hollow nature of the tubes opening in both ends can also be observed. The details of the microstructures of titanate nanotubes can be found in our previous work [21]. Instead, the component ZnO nanoparticles obtained via solution chemistry method showed a spherical morphology with a diameter of about 25 nm (Fig.…”

“…Wang and his co-workers have reported the enhanced photocatalytic activities toward rhodamine B (RhB) degradation over WO 3 /titianate [19] and CdS/titanate nanocomposites [20]. Recent work by our laboratory [21] has demonstrated that titanate nanotubes can effectively improve the photocatalytic efficiency of TiO 2 nanoparticles under visible light illumination. If titanate nanotubes were coupled with ZnO to form the nanocomposites, it is highly possible to achieve novel photocatalytic materials for effective removal of organic pollutants from the industrial wastes, since one can take advantage of the high activities of ZnO nanoparticles and the high absorption capacity of nanotubes.…”

Fabrication and Characterization of Titanate Nanotube Supported ZSM-5 Zeolite Composite Catalyst for Ethanol Dehydration to Ethylene

“…In comparison with TiO 2 nanoparticles, TiO 2 NT offers a larger available surface area and also provides channels for enhanced electron transfer. 38 And TiO 2 NT is usually used as an electron acceptor material. For example, it is used in Dye Sensitized Cell (DSSC) to receive the electron from the excitated dye sensitizer.…”
