In this research, undoped and doped (Fe, Ce, and Ag) antibacterial coatings of nanostructured TiO2 films were prepared by a sol-gel dip coating method. Doped and undoped TiO2 films were excited with ultraviolet (UV) radiation to improve their photo catalytic activity. The antibacterial activity against Staphylococcus Aureus bacteria was studied using an antibacterial–drop test and colony count ...

Photoelectrochemical cell-typed self-powered UV detectors have attracted intensive research interest due to their low cost, simple fabrication process, and fast response. In this paper, SnO2-TiO2 nanomace arrays composed of SnO2 nanotube trunk and TiO2 nanobranches were prepared using soft chemical methods, and an environment-friendly self-powered UV photodetector using this nanostructure as th...

Synthesizing metal oxides through the sol–gel process provides a convenient way for forming a nanostructured layer in wide band gap semiconductors. In this paper, a unique method of introducing dopants into the metal oxide semiconductor is presented. The doped TiO2 is prepared by adding a Cs2CO3 solution to a nanocrystalline TiO2 solution that is synthesized via a nonhydrolytic sol–gel process....

Highly aligned Cu2O, Cu2O/CuO, Cu2O/CuO/TiO2 and Cu2O/TiO2 nanowires arrays on Au substrates were prepared by controlled air annealing of the electrodeposited Cu nanowires and furthered with dip coating. Photoelectrochemical investigations were carried out to determine their potential as photocathodes for water photo-reduction. The photocurrent of the Cu2O nanowires photocathode was found to be...

In this work, the development of a new crystallization technique is reported, using nitrogen plasma (AC) to obtain nanostructured anatase and rutile from amorphous titanium oxide (TiO2). This methodology increases throughput and minimizes thermal effects. Nanostructured amorphous TiO2 was obtained by the sol-gel method and subsequently subjected to AC treatment, at a controlled pressure, applyi...

A novel design has been proposed for facile and rapid build-up of highly tailorable nanostructured multishells on metal oxide particles (graphene/TiOx@TiO2) starting from a mixture powders TiO2 polymethylmetacrylate. We also thoroughly systematically investigated the as-prepared particle surface formation mechanisms specific structure achieved by rapid-concomitant reaction n in microwave cerami...
