“…Formation of nanosized oblate hillocks on the surface of irradiated films was investigated by AFM studies. The shape and size of nanoparticles formed is dependent on the irradiation fluence [686][687][688]. Romero-Gomez et al studied the low energy ion irradiation effect on TiO 2 thin film.…”

“…The redundancy of amorphous carbon in this sample order probably shadowed the occurrence of anatase and Rutile phases of C-N-TiO 2 , which were barely detectable by XRD analysis in Figure 4 b. This aspect was attested by a few authors [ 64 , 65 ] who conveyed that the Raman spectrum of amorphous TiO 2 exhibits no preponderant peaks.…”

The development of durable photocatalytic supports resistant in harsh environment has become challenging in advanced oxidation processes (AOPs) focusing on water and wastewater remediation. In this study, stainless steel (SS), SS/Ti (N,O) and SS/Cr-N/Cr (N,O) anticorrosion layers on SS meshes were dip-coated with sol gel synthesised C-N-TiO2 photo catalysts pyrolysed at 350 °C for 105 min, using a heating rate of 50 °C/min under N2 gas. The supported C-N-TiO2 films were characterised by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and Raman spectroscopy. The results showed that C-N-TiO2 was successfully deposited on anticorrosion coated SS supports and had different morphologies. The amorphous C and TiO2 were predominant in C-N-TiO2 over anatase and rutile phases on the surface of SS and anticorrosion supports. The C-N-TiO2 coated films showed enhanced photocatalytic activity for the decolouration of O.II dye under both solar and UV radiations. The fabricated C-N-TiO2 films showed significant antibacterial activities in the dark as well as in visible light. Herein, we demonstrate that SS/Ti(N,O) and SS/Cr-N/Cr(N,O) anticorrosion coatings are adequate photocatalytic and corrosion resistant supports. The C-N-TiO2 photo catalytic coatings can be used for water and wastewater decontamination of pollutants and microbes.

“…Titanium dioxide (TiO 2 ) remains one of the most prominent members of the metal oxide family owing to its high chemical and thermal stability, excellent photoactivity, biocompatibility and availability in the form of three different polymorphs (anatase, brookite and rutile). 8,9 There are a few reports, which have discussed SHI irradiation-induced structural changes in TiO 2 , for example, from amorphous to anatase, 10 rutile, 11,12 and mixed-phase; 12 and anatase to amorphous, 13 rutile, 14 and mixed-phase 15 transformations. SHI irradiation induced effects have also been studied on doped TiO 2 .…”
