Photocatalytic Performance of Sol-Gel Prepared TiO₂ Thin Films Annealed at Various Temperatures.

ABSTRACT: Titanium dioxide (TiO₂) in the form of thin films has attracted enormous attention for photocatalysis. It combines the fundamental properties of TiO₂ as a large bandgap semiconductor with the advantage of thin films, making it competitive with TiO₂ powders for recycling and maintenance in photocatalytic applications. There are many aspects affecting the photocatalytic performance of thin film structures, such as the nanocrystalline size, surface morphology, and phase composition. However, the quantification of each influencing aspect needs to be better studied and correlated. Here, we prepared a series of TiO₂ thin films using a sol-gel process and spin-coated on p-type, (100)-oriented silicon substrates with a native oxide layer. The as-deposite
