Titanium Dioxide Nanomaterials: Synthesis and Applications

Abstract

The emergence of nanomaterials as an exciting class of materials is the main reason for the high demand for nanoparticle utility and practical applications in the modern era. At present, the green synthesis process has proved to be the most advanced method in the production of nanoparticles. In green synthetic method, plant or its part is used for bioreduction of metal ions to their elemental form. Nanoparticles manufactured by this method are simple, accessible, eco-friendly and available at low cost and can be easily scaled up for larger operations. For this reason, in the modern era, their application is being done in areas like biosensors, lithium ion batteries, water purification, electrocatalysis, coating, photo-thermal therapies, drug delivery, etc. Among the different metal and metal oxide nanoparticles TiO2 is one of the most promising nanoparticles due to their unique structural chemical and morphological properties. Green synthesis of TiO2 nanoparticles by using extract of different biological agent is one of the most growing areas of research. Phytochemicals, enzymes, and proteins, all bioactive components, play an essential role in the production of nanoparticles. The potentiality of titania (TiO2) to operate as an antibacterial and photocatalytic agent is one of the topics that has garnered the most interest from the scientific community. This review provides an overview of different available green synthesis method for the fabrication of TiO2 nanoparticles and also highlighted the different industrial applications of TiO2.
