“…Nanostructural modifications of titanium dioxide are of great research interest, particularly in the development of promising functional media for renewable energy sources (i.e., solar cells and the photochemical decomposition of water) [1][2][3][4] , selective organic synthesis with atomic precision for direct C-H functionalization of a variety of organic molecules 5 , the manufacture of efficient photoelectric transducers and memristor memory cells 6 , the development of photocatalysts for the removal of organic impurities [7][8][9] , and other applications [10][11][12] . The optical gap width of stoichiometric TiO 2 (>3.1 eV) determines its photocatalytic activity under the action of near -UV radiation, which constitutes only a small percent of the solar spectrum 13 .…”

The catalytic activity of nanotubular titanium dioxide films formed during the oxidation of acetone to carbon dioxide under the action of visible light with a wavelength of 450 nm was found to be approximately 2 times higher compared to standard titanium dioxide (Degussa P25). The nanotubular films were grown by the anodization of titanium foil using an original technique. Diffuse reflectance spectra of the films are attributed to enhanced activity in the visible spectrum by the nonstoichiometry of titanium dioxide near the interface between the nanotubular film and the titanium foil substrate.

“…Фотокаталитические процессы в последние годы находят все более широкое промышленное применение для разложения вредных органических соединений, преобразования солнечной энергии в химическую и электрическую, создания сенсоров и устройств нанофотоники, ускорения процессов органического синтеза и других целей. При этом, наиболее распространённым гетерогенным фотокатализатором является анатаз, что связано с его высокой фотокаталитической активностью, высокой химической стабильностью, низкой стоимостью и отсутствием токсичности (Rempel et al, 2015). Однако фотокатализ с использованием анатаза имеет ряд существенных недостатков.…”

Аннотация. Рассмотрена перспектива применения синтетических титаносиликатов в качестве материала для областей фото-и гетерокатализа. Изучена фотокаталитическая активность аналогов минералов линтисита, иванюкита, зорита, коробицынита, ситинакита по отношению к раствору ферроина в видимой части света при λ = 546 нм. Определено, что наибольшей степенью разрушения органического индикатора обладает смесь IONSIVE-IE+ETS-4+SIV (68.72 %), а также синтетический аналог иванюкита SIV (42.63 %) и коробицынита SKR (31.48 %). Показано, что на основе титаносиликата АМ-4 можно получить перспективный, редкий, оснóвный гетерогенный катализатор для органического синтеза при его обработке раствором кислоты и перехода кристаллической структуры в соединение SL3.

“…Most of the methods are so expensive and complex, especially for controlling the size of particles and uniformity of their size. However, laser ablation is one of the emerging methods for synthesizing the nanostructure of Cadmium Oxide (CdO) [109][110][111][112][113][114][115][116][117][118][119][120][121]. The most important characteristic of this method is that it is possible to control the size of produced material by changing various parameters such as laser wavelength, laser pulse duration, pH of solution, added surfactant and temperature .…”

The effects of substrate temperature on the structural, optical, medical and electrical characteristics of Cadmium Oxide (CdO) films are investigated in the current study. Films are deposited on glass substrate at different temperatures, ranged between 450-600 ºC, using Spray Pyrolysis Technique. According to XRay Diffraction (XRD), it is found that the films are polycrystalline and Cadmium Oxide (CdO) is of a hexagonal wurtzite structure which the preferred direction of its crystal plane is (002). The maximum optical transmittance of films is more than 85%. The size of crystallites is calculated with the maximum value in 500º C. Furthermore, Cadmium Oxide (CdO) nanoparticles were synthesized in deionized water by laser ablation of Cadmium plate. In the current paper, the effects of laser pulse energy and wavelength on the characteristics of Cadmium Oxide (CdO) nanoparticles were studied. Analyses of Transmission Electron Microscope (TEM) were confirmed that size distribution of Cadmium Oxide (CdO) nanoparticles is reduced by increase in laser pulse energy. Fluorescence spectrum of Cadmium Oxide (CdO) nanoparticles shows violet emission accompanied by blue and green band. UV emission with high intensity shows that nanostructure of Cadmium Oxide (CdO) is of a little deficiency. Also, the current study aims to study the linear and non-linear optical characteristics of Cadmium Oxide (CdO) nanoparticles and their applications. Firstly, fluorescence spectrum, as a linear characteristics of Cadmium Oxide (CdO), as well as second harmonic generation and two photons absorption, as non-linear characteristics of Cadmium Oxide (CdO), are studied. Then, some aspects of medicinal and pharmaceutical applications of Cadmium Oxide (CdO) nanoparticles for eliminating cancer cells such as the effect of Cadmium Oxide (CdO) nanoparticles on DNA of human cancer cells and the interaction of Cadmium Oxide (CdO) nanoparticles with DNA of cancer cells are originally investigated. It should be noted that the range of considered parameters are separately clarified and explained in each of related sections (Figure 1).
