Titanium is indeed a metal, known for its high strength, lightweight, and exceptional corrosion resistance. Discovered in 1791 by William Gregor, titanium is the ninth most abundant element in the Earth’s crust. Its impressive properties stem from its durable yet light nature, making it ideal for aerospace, military, medical implants, and even sporting goods. Despite its abundance, extracting titanium from its ore is costly and complex, involving the Kroll process, which contributes to its premium price. However, its advantages, such as biocompatibility and the ability to withstand extreme environments, often outweigh the cost for many applications. Additionally, titanium’s ability to alloy with metals like aluminum and vanadium further enhances its utility by improving strength and thermal properties.

The sol-gel process is a popular method for coating titanium dioxide. often employed in film and fiber production. It involves preparing a solution with titanol salt precursor. which then undergoes hydrolysis and shrinkage reactions to create a gel. This gel is then applied onto the substrate and heated at high temperatures to produce the desired titanium dioxide layer. The outcome of the coating greatly depends on how well the precursor is concentrated. the speed of hydrolysis. and the temperature during annealing. With expert supervision and careful management of these variables. excellent results can be achieved.

Q photocatalytic activity of titanium dioxide and zinc oxide

Titanium dioxide (TiO2) and zinc oxide (ZnO) are two semiconductor materials that have been widely used in photocatalysis due to their favorable band gap energy and high stability. 1. Titanium Dioxide (TiO2): With a band gap of 3.2 eV, titanium dioxide is one of the most extensively studied photocatalysts due to its strong oxidizing power, high chemical stability, non-toxicity, and low cost. It can absorb ultraviolet light (< 387 nm) and produce electron-hole pairs. These electrons and holes can then react with water and oxygen to produce hydroxyl radicals and superoxide ions, respectively. These reactive species can then decompose organic pollutants present in the environmental or industrial waste. 2. Zinc Oxide (ZnO): ZnO, with a bandgap of 3.37 eV, has also been extensively used as a photocatalyst for the degradation of numerous pollutants. Similar to TiO2, ZnO can generate electron-hole pairs upon absorption of UV light. The photogenerated carriers of ZnO show strong oxidation and...

There are some products that contain titanium dioxide as a colorant or additive. Titanium dioxide is generally considered safe by the U.S. Food and Drug Administration FDA. Although large amounts of the additive may have negative health effects. its use in food is still subject to debate and research. Limiting consumption of processed foods containing it is always a good idea.
