Surface Modifications and Growth of Titanium Dioxide for Photo-Electrochemical Water Splitting

Focusing on the growth of titanium dioxide thin films, this thesis explores their application in photo-electrochemical processes, particularly water splitting. It delves into the theory of semiconductor-liquid junctions and examines the significant role of plasmonic enhancement through gold nanoparticles. A comprehensive literature review highlights potential mechanisms behind this enhancement, specifically with Nb-doped TiO2. Additionally, it discusses how temperature and pressure can influence the phase and morphology of thin films produced via pulsed laser deposition.
