Titanium dioxide (TiO2) P25 is a high-purity, nano-grade powder (20-25 nm particle size) widely recognized as a standard material in scientific research, particularly for photocatalysis applications. It consists of a mixed anatase-rutile phase, offering exceptional photocatalytic activity under UV light, enabling the degradation of organic pollutants in air and water purification systems. This specialty chemical is also used as a pigment in paints, coatings, and plastics for its opacity and brightness, providing a white, reflective finish in construction and automotive industries. In cosmetics, it serves as a UV blocker in sunscreens and makeup by scattering sunlight. The food industry employs it as a whitening agent in candies, chewing gum, and dairy products. Its nanoscale properties enhance its versatility in environmental remediation, self-cleaning surfaces, and advanced materials research.
