ABSTRACT

Titanium dioxide (both rutile and anatase) has mainly been used as a pigment for paints, plastics, paper, glass, leather, and cosmetics (sunscreen). The key functional property of TiO2 for these applications is its bright white color and resistance to decoloration under UV light. Awareness is growing, however, that TiO2 may soon become a strategic raw material in the processing of photosensitive semiconductors for solar energy conversion.
