Hydrothermal Synthesis, Optical and Photocatalytic Properties of Yttrium-Doped Titanium Dioxide Nanoparticles
Yttrium-doped titanium dioxide nanoparticles are synthesized using a hydrothermal method. Titanium dioxide nanoparticles with different yttrium content are characterized using infrared Fourier spectroscopy, diffuse reflectance spectroscopy, transmission electron microscopy, scanning electron microscopy, X‑ray diffraction, and small-angle X-ray scattering. Optimal processing modes (washing with solvents and subsequent thermal annealing) are selected to obtain particles with improved photocatalytic properties and minimal carbon content of residual organic derivatives. Yttrium-doped titanium dioxide nanoparticles demonstrate higher photocatalytic activity compared to the undoped sample, which is explained by the formation of additional energy levels within the band gap that reduces the intensity of the reverse recombination process. The results obtained facilitate the selection of the most optimal modes and methods for obtaining titanium dioxide nanoparticles with high photocatalytic activity.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
