When designing new semiconductor materials for solar energy conversion. the potential of the conduction band CB and valence band VB edges. also known as energy levels. plays a critical role in facilitating charge transfer. The titanium dioxide TiO2 conduction band end compared to the general hydrogen electrode NHE is around -0.5 V. while the valence band end compared to NH3 is approximately 2.5-3.0 V. These values may vary significantly depending on factors like pH. temperature. and TiO2 type rutile or anatase. It is worth noting that TiO2 has a wide-band gap of about 3.0 eV. meaning it requires UV energy to promote electron movement from the valence to the conduction band. Understanding the correlation between the NHE potential and energy band diagram is crucial for efficient photocatalytic or photoelectrochemical cells e.g.. using TiO2 for water decomposition into hydrogen and oxygen and dye-sensitized solar cells. In essence. the arrangement of energy levels determines the feasibili...

Titanium dioxide is a naturally occurring mineral that is often refined for use in a range of products. It’s commonly used in sunscreens due to its ability to block and scatter UV rays, thereby protecting the skin from sun damage. Additionally, it’s used as a pigment for providing whiteness and opacity to a variety of products like paints, plastics, papers, inks, foods, medicine, toothpaste, and most tooth powders. It is also found in cosmetics and skincare products to improve their texture and coverage. Despite its widespread use, there are some concerns about its safety, particularly when inhaled or ingested in high quantities.
