A mesoporous titania thin film with a pseudo-single-crystal framework was synthesized on a lanthanum aluminate single-crystal substrate by a surfactant-assisted sol-gel method and liquid-phase epitaxial growth. The crystal lattices were well aligned within the titania framework. The highly energetic {001} facet was exposed on the top surface, which significantly enhanced the photocatalytic activity.

Heterojunction formation between BiVO nanomaterials and benchmark semiconductor photocatalysts has been keenly pursued as a promising approach to improve charge transport and charge separation via interfacial electron transfer for the photoelectrocatalytic degradation of recalcitrant pharmaceutical pollutants. In this work, a heterostructured TiO/Mo-BiVO bilayer photoanode was fabricated by the deposition of a mesoporous TiO overlayer using the benchmark P25 titania catalyst on top of Mo-doped BiVO inverse opal films as the supporting layer, which intrinsically absorbs visible light below 490 nm, while offering improved charge transport. A porous P25/Mo-BiVO bilayer structure was produced from the densification of the inverse opal underlayer after post-thermal annealing, which was evaluated on photocurrent generation in aqueous electrolyte and the photoelectrocatalytic degradation of the refractory anti-inflammatory drug ibuprofen under back-side illumination by visible and UV-Vis light.

Poor wear- and corrosion-resistance of 316L SS implants are critical problems in orthopedic implants. This study aims to improve the wear- and corrosion-resistance of 316L SS through surface coating. In this study, a bilayer composite coating consisting of polyether ether ketone (PEEK) as the first layer, and titania (TiO)- and Cu-doped mesoporous bioactive glass nanoparticles (Cu-MBGNs) were deposited as the second layer on a 316L SS electrophoretic deposition (EPD).

Titania (TiO) is one of promising photo catalysts for its high ability to resistant photo corrosion and environmental friendliness, but its photocatalytic activity is too low to be used in industry. To find an approach to solve this problem, graphene oxide (GO), tungsten trioxide (WO) and TiO composite with hollow mesoporous structure was prepared by a two-step spray drying method. The composite was used as raw material to constitute a membrane onto ITO glass to form a membrane photo-anode.

This work examines the photocatalytic capacity of FeO-TiO catalysts for inactivating Enterococcus faecalis in water and compares it to a peroxide-assisted process. The influence of HO, PMS, pH, and temperature is assessed. Material stability and free radical species involved in disinfection are also evaluated.

Article Synopsis
- Mesoporous titania thin films have potential applications in various fields such as sensors, batteries, and solar cells, but traditional methods of creating these films often require high temperatures that can damage the structures.
- A new approach using UV irradiation is presented as a low-temperature, energy-efficient alternative that achieves comparable crystallinity and size to conventional methods, without the drawbacks of high-temperature calcination.
- This UV method allows for the creation of diverse film morphologies and maintains consistent optical properties, demonstrating its adaptability with different titanium precursors for thin film fabrication.
