The Si-doped TiO2 nanotubes photocatalysts was synthesized by anodic oxidation method, which used Na2SiF6/HF as an electrolyte, and was characterized by means of SEM, XRD, DRS and EDX. TiO2 nanotubes composed of anatase phase and rutile phase, and Si was highly dispersed on the wall of TiO2 nanotubes. The photocatalytic activity of the Si-doped TiO2 nanotubes was investigated for photocatalytic degradation of gaseous toluene. It was found that the photocatalytic activity of Si-doped TiO2 nanotubes, which prepared by 0.03 mol x L x (-1) Na2SiF6/HF and calcined at 400 degrees C for 1 h, was the highest. The conversion of toluene was 60% over the prepared Si doped TiO2 nanotubes under UV light, which was one times higher than that of pure TiO2 nanotubes.

Herein, CuBiO microspheres were first deposited on TiO nanotube arrays to develop a p-n CuBiO/TiO heterojunction by a facile hydrothermal protocol. The variations in the photoinduced open-circuit potential, photocurrent, and electrochemical parameters of the nickel-plated magnesium alloy (Mg/Ni) demonstrated the remarkably strengthened photoelectrochemical efficiency and photocathodic protection (PCP) capability caused by the CuBiO modification. This enhancement is attributed to establishing a built-in electric field and intensified light absorption in a broadened wavelength spectrum, confirmed by the valence band XPS and ultraviolet-visible spectra.

Titanium (Ti) and Ti alloy are the most widely used implant metals, but the limited bioactivity hinders the further clinical application. Aiming to enhance their osteogenesis, dual biomimetic strategies were utilized to decorate the surface of Ti by topological and biochemical cues. Firstly, a series of concentric circles with TiO nanotubes on Ti were fabricated by photolithography and anodic oxidation.

In this work, TiO anatase nanotubes (NTs) were synthesized using a straightforward, two-step anodic oxidation method. To tackle with the optical and electrical properties of the material, a thin layer of tantalum was sputtered onto the nanotube surface. The microstructure of the modified material was analyzed using scanning and transmission electron microscopy (SEM and TEM), while changes in chemical bonding were examined by utilizing X-ray photoelectron spectroscopy (XPS).

Due to their outstanding physicochemical properties, carbon nanotubes (CNTs) have been widely studied and applied in the nanoscience and nanotechnology fields. Herein, Fe-based catalysts were prepared by the impregnation method using AlO, SiO, ZrO, TiO and SnO supports and were used for CNT synthesis from -hexane under different reaction times and temperatures. It was found that the metal-support interaction and FeO particle size of Fe-based catalysts regulated CNT growth.
