ABSTRACT
Titania is a well-researched material due to the stability of its chemical structure, biocompatibility, and physical, optical, and electrical properties. Its photocatalytic properties have been utilized in various environmental applications to remove contaminants from both water and air [1]. Titania-based photocatalytic systems are used for a variety of applications such as decomposition of unwanted and toxic organic compounds, destruction of pollutants from contaminated water and air, and killing of harmful bacteria and cancer cells [2]. The unique feature of the photocatalytic process is that it breaks down the pollutants and harmful organic compounds into simple molecules such as carbon dioxide and water [3]. Due to its stability in harsh environments, titanium dioxide (TiO2) has the potential to be the material of choice for gas sensors that operate at temperatures above 400°C [4].
