Three-dimensional (3D) TiO2 hierarchical structures with various microstructures have been successfully synthesized via a surfactant-free and single-step solvothermal route, in which hydrochloric acid (HCl), nitric acid (HNO3), and acetic acid (HAc) are employed as the acid medium, respectively. The effects of acid medium on the microstructures and properties of 3D TiO2 hierarchical structure h...

The over expression of thioredoxin domain-containing protein 5 (TXNDC5) can promote the growth of castration-resistant prostate cancer (CRPC). A novel highly sensitive photoelectrochemical (PEC) aptsensor was developed for the detection of TXNDC5 by using the nanohybrids (TiO2 NRs/NCQDs) of nitrogen-doped carbon quantum dots (NCQDs) and TiO2 nanorods as the photo-to-electron conversion medium. ...

Herein, we have fabricated rutile TiO2 nanorod-coupled α-Fe2O3 by a wet-chemical process. It is demonstrated that the visible activities for photoelectrochemical water oxidation and for degrading pollutant of α-Fe2O3 are greatly enhanced after coupling a proper amount of rutile nanorods. The enhanced activity is attributed to the prolonged lifetime and improved separation of photogenerated char...

A series of CuO-Cu2O/TiO2 nanocomposite samples were prepared by the sol-gel method. Before applying the sol-gel method, the Cu(OH)2 nanostructure on Cu powders were formed by in-situ solution treatment. The samples were characterized through some techniques and the photocatalytic performance of CuO-Cu2O/TiO2 nanocomposites for gas-phase 2-propanol photo-oxidation under UV and sunlight type ill...

Constructing plasmonic-semiconductor nanoarchitecture provides a photocatalytic platform for enhancing solar energy conversion. The excitation and extraction of energetic carriers are critical improving efficiency, which can be affected by the geometric features plasmonic structures. An extensive study on morphology dependent hot electron utilization is desirable but challenging. In this paper,...

The surface area of a photonic crystal biosensor is greatly enhanced through the incorporation of a porous TiO2 film possessing the structure of nanorods into the device. The film is deposited by the glancing angle deposition technique in an e-beam evaporation system. The sensitivity of high surface area sensors is compared with sensors without the high surface area coating. Results for detecti...

This work reports a procedure to modify the surface nanostructure of TiO2 anatase thin films through ion beam irradiation with energies in the keV range. The irradiation with N ions leads to the formation of a layer with voids at a depth similar to the ion projected range. By setting the ion projected range few tens of nanometres below the surface of the film, well ordered nanorods appear align...

Infections caused by microorganisms are a global public health problem that continually demands new antimicrobial strategies. The generation of reactive oxygen species (ROS) photocatalytic materials is an attractive approach to combat microbes. Along these lines, titanium dioxide (TiO2) constitutes outstanding light-driven ROS generator. However, the wide bandgap this semiconductor limits its u...
