• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Long Term Exposure: Lungs may be affected by repeated or prolongated exposure. This may result in chronic inflammation. This substance is possibly carcinogenic to humans if inhaled.
• Regulation and Approval: The FDA approved the use of titanium dioxide in food in 1966. In a brief statement to industry issued in June 2023, the FDA claims it has evaluated EFSA's opinion and concluded that titanium dioxide is safe.; The European Commission banned titanium dioxide as a food additive in 2022 due to concerns about genotoxicity.
• Industrial Usage: Titanium dioxide is a semiconducting material and chemically inert, widely used in different applications.; Titanium dioxide is extensively used as a white pigment in various applications. It offers advantages such as high stability, non-toxicity, and low cost. The two useful crystal forms for pigment applications are anatase and rutile.; Titanium dioxide is a food additive used to enhance the color of food, prevent spoilage, and extend shelf life. It's also used as a thickener and to keep powdered foods from clumping.; Used in solar panels to reduce air pollutants. Titanium dioxide particles scatter visible light effectively due to their high refractive indices.
• Environmental Applications: Titanium dioxide has emerged as an excellent photocatalytic material for environmental applications.; Factors such as particle morphology, crystal structure, and electronic and optical properties influence its photocatalytic activity.; Photocatalytic oxidation technology using titanium dioxide can efficiently degrade organic pollutants into harmless inorganic substances.
• History and Development: Titanium dioxide is found in many minerals, sands, soils, and dusts on Earth. For example, titanium oxides are found in black magnetic sand in Cornwall, discovered by William Gregor in 1791. In 1795, M H Klaproth isolated the oxide from mineral rutile in Hungary. However, the first commercial production of titanium dioxide pigment did not take place until the 1920s.; Research on titanium dioxide's photocatalytic properties dates back to the 1970s. It has been found effective in degrading pollutants such as polychlorinated biphenyls and cyanide. Titanium dioxide has advantages over traditional catalytic methods in terms of photocatalytic reaction conditions, pollution-free process, and recyclability.

TiO₂–SiO₂ Catalyzed Eco-friendly Synthesis and Antioxidant Activity of Benzopyrano[2,3-d]pyrimidine Derivatives

10.1002/jhet.2856

The research focuses on the eco-friendly synthesis and antioxidant activity of benzopyrano[2,3-d]pyrimidine derivatives, which are compounds known for their pharmacological and biological activities. The purpose of the study was to develop a cost-effective, environmentally benign method for synthesizing these derivatives using a three-component one-pot tandem approach. The researchers used salicylaldehydes, malononitrile, and secondary amines as starting materials, catalyzed by a TiO2–SiO2 catalyst under solvent-free conditions at 80°C. The methodology offered several advantages, including mild experimental conditions, reusability of the catalyst, and high product yields. The study concluded that the synthesized compounds, particularly those bearing a 2-OMe group on the hydroxyphenyl group (4g, 4h, and 4i), exhibited good antioxidant activity, as evidenced by NO, DPPH, FRAP, and H2O2 assays, and were comparable to ascorbic acid in their activity. The presence of the OCH3 group was identified as a significant factor contributing to the high antioxidant activity of these compounds.

Preparation and photocatalytic activity of Nd-modified TiO₂ photocatalysts: Insight into the excitation mechanism under visible light

10.1016/j.jcat.2017.07.017

The research investigates the synthesis, characterization, and photocatalytic properties of neodymium (Nd)-modified titanium dioxide (TiO2) nanoparticles prepared via the hydrothermal method. The study aims to enhance the visible light photocatalytic activity of TiO2 by doping it with Nd in the range of 0.1 to 1.0 mol%. The photocatalysts were characterized using various techniques, including diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), X-ray fluorescence (EDX), Brunauer–Emmett–Teller (BET) method, X-ray powder diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), and photoluminescence spectroscopy (PL). The results showed that the Nd-modified TiO2 exhibited high photocatalytic activity under visible light, with the highest activity observed for the sample modified with 0.1 mol% Nd3+. This sample had a surface area of 124 m2/g and an average crystal size of 10.9 nm. The study also explored the excitation mechanism under visible light and concluded that the up-conversion process was not responsible for the degradation of phenol under visible light irradiation. The enhanced photocatalytic activity was attributed to the increased adsorption sites, BET surface area, decreased crystallite size, and prevention of electron-hole recombination.
