“…For obtaining TiO 2 -SnO 2 nanocomposites in the form of both powders and films, various methods are used, such as sol-gel [30][31][32][33], hydrothermal synthesis [34][35][36], chemical vapor deposition [37], spray and laser pyrolysis [38][39][40][41], coprecipitation [42,43], and green [44]. Each of these methods has its advantages and practical application when a certain nanocomposite structure is needed.…”

The paper presents the results of characterization and study of adsorption-photocatalytic properties of commercial and synthesized-by-hydrothermal method TiO2 and TiO2-SnO2 nanocomposites. Hydrothermal synthesis of TiO2-based nanocomposites was performed in two ways: single-stage and two-stage methods. Characterization was carried out by XRD, X-ray fluorescence method, XPS, EPR, PL, and low-temperature adsorption-desorption of nitrogen, which showed that TiO2-SnO2 nanostructured composites were obtained with tin(IV) oxide content of 10 wt.% and had acidic surface and different porous structures. Besides, modification of a commercial sample with tin(IV) oxide led to a slight decrease in the specific surface area, while modification of a synthesized-by-hydrothermal method TiO2 sample led to an increase. It was found that sorption properties of the obtained nanocomposites and pure TiO2 are better towards anionic dyes. Photocatalytic activity, on the contrary, is higher towards cationic dyes, which is consistent with additional studies on the destruction of these dyes. It was established that in terms of photocatalytic activity, TiO2-SnO2 nanocomposites are more promising than solid solutions, and modification of TiO2 with tin(IV) oxide, in general, leads to improvement of its photocatalytic activity.

“…The thin film of TiN and TiO 2 can be synthesized by numerous techniques, such as chemical vapor deposition (CVD) [15,16], physical vapor deposition (PVD) [17,18], and reactive sputtering [19]. However, these techniques present certain disadvantages, such as high cost and complexity of equipment, low working pressure, of the order of 10 −3 mbar, high temperature above 600 °C and long duration [1].…”

The cathodic cage plasma deposition (CCPD) is an advanced technique recently developed from an active screen plasma nitriding system, which has been used for thin film deposition such as titanium nitride and titanium dioxide (TiO 2). These coatings can improve the physical, mechanical, and optical properties of numerous materials, and such coatings can be developed by several techniques. Unfortunately, the conventional deposition techniques exhibit certain drawbacks, including high cost, the complexity of the operation, very low pressure, and high processing temperature; as a result, CCPD is an advantageous technique. In this review, brief information on the deposition of titanium nitride and oxide coatings on steel alloys, titanium, glass, and silicon substrates, and the effect of control parameters on deposition efficiency is provided. The effectiveness of this system for the synthesis of thin films on various substrates, including insulators and conductors, is also summarized. The recent developments and applications of CCPD for titanium-based coatings are described in detail.

“…In order to obtain TiO 2 film, physical vapor deposition (Kansal et al , 2007), chemical vapor deposition (Rasoulnezhad et al , 2017), sol-gel method (Kralova et al , 2014; Chatzitakis et al , 2017; Lee et al , 2018) and magnetron sputtering (Yuan et al , 2017) have been applied. However, some results are not very ideal in some details.…”

Purpose This paper aims to investigate the photocatalytic activity of zinc doped MAO-TiO2 films under the optimum MAO treatment condition. Design/methodology/approach The coating was prepared by micro arc oxidation, and the influence of doping on the properties of the coating was also investigated. Findings The results show that the BET surface area is 78.25±0.03m2/g, total pore area is 76.32 ± 0.04m2/g, and the total pore volume is 0.2135 ± 0.0004cm3/g. The degradation ratio of the film electrode with Zn-doped in methyl orange solution is up to 94%. When the react circles is 10 times, the degradation ratio is up to more than 85% and remains steady. With the different reaction conditions, these kinetics of the reactions show some different formulas. Originality/value A kinetic equation for photocatalytic activity is established.
