Mesoporous TiO2 Thin Films: State of the Art

Mesoporous TiO2 thin films (MTTFs) thank to their particularly high surface area, controlled porosity, high flexibility in composition and surface design, are promising candidates in different application fields such as sensors, self-cleaning coatings, lithium-ion batteries (LIBs), photocatalysis and new generation solar cells. This chapter is focused on the synthetic and post synthesis aspects that can affect the TiO2 mesoporous structure and consequently the MTTFs properties. In particular, after a brief summary of TiO2 properties, all experimental conditions to prepare MTTFs are reviewed as well as the main characterization techniques employed to study their physico-chemical and photocatalytic properties. An overview of the main applications of MTTFs is also proposed, mainly focused onto the use of MTTFs in sensors and LIBs.
