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...

Q can a titanium ring be resized

Titanium rings are not usually resized. Titanium is a very hard metal. making it difficult to cut and re-solder. If your titanium ring is too small. you may need to have a new one made.
