“…2c. It can be found that diffraction peaks appeared at 25.4° and 48°, which can be attributed to the (101) and (200) orientations of the anatase TiO 2 (JCPDS No.21-1272) [36]. No characteristic peak of any impurity is probed, which demonstrates that the sample fabricated by this method has high phase purity.…”

High specific surface area three-dimensional pine tree-like hierarchical TiO2 nanotube array films loaded with Ag nanoparticles were successfully prepared by one-step hydrothermal reaction combining with simple and feasible magnetron sputtering. The composite Ag/TiO2-branched nanotube arrays show outstanding photocatalytic property, which is attributed to the boost of plasmonic enhancement carrier generation and separation, higher specific surface area, higher organic pollutant absorption, faster charge transport, and superior light-harvesting efficiency for efficient charge collection. The work provides a cost-effective and flexible pathway to develop high-performance photocatalyst or optoelectronic devices.

“…The rutile phase of TiO2 (simple tetragonal) has applications in the construction of electric capacitors, filters, power circuits and capacitors due to its high dielectric constant [15]. TiO2 has been extensively studied in various photo catalytic systems, including photodegradation of volatile organic compounds, hydrogen production and other environmental applications due to its n-type semiconductor properties, with a range of 3.0 to 3.2 eV (depending on crystallographic variants), low toxicity potential, good chemical and thermal stability, surface acidity and selectivity [16][17][18][19]. The properties and applications of titanium oxide are summarized in Table 1.…”

Titanium dioxide (TiO2) presents particular importance, due to its general properties in a wide range of fields, such as catalysis, photocatalysis and antibacterial agents and as nano-paint (self-cleaning). Physical and chemical characteristics of TiO2, particle size and shape, phases of crystalline TiO2 with band gaps that rutile TiO2 of 3.0 eV and anatase TiO2 of 3.2 eV, determine the photocatalytic performance of TiO2. This review presents the theoretical concepts of the structure properties of this oxide and the elaboration methods that make TiO2 the ideal candidate for catalytic applications.

“…A síntese seguiu uma adaptação de uma metodologia conhecida na literatura (FAN et al, 2016). Para tanto, diluiu-se 10 ml de isopropóxido de titânio em 30 ml etanol, o sistema foi mantido sob agitação constante por 5 min, seguiu-se da adição gota-a-gota de 20 ml de ácido acético com posterior adição de 1 ml ácido sulfúrico.…”

Nanoparticles of titanium oxide (TiO 2 ) have high potential for environmental application due to their photocatalytic properties. However, to optimize such properties, particle size, structure, phase and surface area are parameters that need attention. The use of different synthesis methods makes possible to control these characteristics. In this work, TiO 2 powders were obtained by the microwave assisted solder gel and sol-gel methods to evaluate the crystallinities, phases and morphologies obtained. The diffractograms indicate that the anatase phase was obtained for both methodologies, with the crystallinity being lower for the solvothermic methodology and for the sol-gel methodology when the calcination was not performed. Furthermore, in the sol-gel methodology, for higher calcination temperatures, less formation of aggregates occurs, in addition it was possible to observe the formation of TiO 2 rings, although with irregular presence.
