Abstract

Chemical industry is facing major challenges to dispose environmentally hazardous waste materials. Heterogeneous catalysis is a fascinating field which offers eco-friendly treatment steps and minimum waste; heterogeneous photocatalytic degradation of pollutants being the most desired method in this direction. Titania is well known as a cheap, stable, nontoxic, and efficient photocatalyst without secondary pollution. However, pure TiO2 materials usually have very low quantum efficiency and poor performance in the visible region of light, thus restricting its extended applications in photocatalysis. Use of nonmetals or other metals as dopant systems is the most practicable approach for shifting the absorbance of TiO2 to the visible region. These dopant materials bring forth new properties and enhanced activity due to structural and electronic modifications on TiO2. Sol-gel synthesis of metal oxides is a widely accepted method for the preparation of such materials, particularly to incorporate ions in the gels. This short communication discusses the sol-gel preparation of TiO2, its properties, and photocatalytic applications in waste remediation. A brief review on the modifications adopted for developing TiO2 photocatalysts of improved performance is presented with examples.
