Phase-Dependent Photocatalytic Activity of TiO2 – the Role of Intrinsic and Extrinsic Factors
The doctoral thesis delves into the phase-dependent photoactivity of anatase and rutile TiO2, explored through various photocatalytic reactions involving oxidation and reduction processes. The investigation of the influential factors involved in this dependency has led to the identification of two primary categories: intrinsic factors, which relate to the physicochemical and characteristic properties of the materials themselves, and extrinsic factors, which are associated with the nature of the specific reactions and their corresponding reaction conditions. The study demonstrates that the photoactivity of TiO2 is relative to both intrinsic and extrinsic factors, and sheds light on the mechanisms underlying photocatalysis. By optimizing these factors, it is possible to enhance the photoactivity of TiO2 and develop more efficient and practical photocatalytic systems. These findings reveal the fundamental mechanisms underlying photocatalysis and pave the way for the development of more suitable photocatalysts for particular reactions, which are crucial for optimizing and realizing the practical use of photocatalysis for addressing the energy crisis and climate change.
