Book excerpt: This outstanding thesis provides a wide-ranging overview of the growth of titanium dioxide thin films and its use in photo-electrochemicals such as water splitting. The context for water splitting is introduced with the theory of semiconductor-liquid junctions, which are dealt with in detail. In particular plasmonic enhancement of TiO2 by the addition of gold nanoparticles is considered in depth, including a thorough and critical review of the literature, which discusses the possible mechanisms that may be at work. Plasmonic enhancement is demonstrated with gold nanoparticles on Nb-doped TiO2. Finally, the use of temperature and pressure to control the phase and morphology of thin films grown by pulsed laser deposition is presented.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoelectrochemical (PEC) water splitting has been widely regarded as one of the most promising routes for hydrogen production from water. Titanium dioxide (TiO2) and TiO2u2013 based) materials were mostly used for that purpose. However, performance limitations require innovative strategies to maximize the efficiency of such systems. Nano-structuration and surface modification of TiO2 substrates are both necessary to optimize water splitting under solar light. In this work, we successfully decorated TiO2 nanorods (TNRs) arrays with thin layers of a nickel metal organic framework (MOF) using a layer-by-layer growth process. Ni-BDC (NBF) was selected as a surface photosensitizer and co-catalyst for the oxygen evolution reaction (OER). The morphology of the final product contains vertically-oriented TNRs decorated with NBF nanoparticles, forming a thin layer nanostructure. The loading concentration of NBF was found to impact the resistance, electrons transfer and photo-response of the photo-electrode, and fine tuning was required to optimize the photoactivity. After optimization, this unique architecture of NBF@TNRs photoanodes shows an enhanced OER photo-activity, with a photocurrent of 0.46 mA cm-2 under 100 mW/cm2 UV + Visible light intensity (42.4 u00b5A cm-2 under 63 mW/cm2 intensity of visible light >420 nm) which are ~20 times higher than on bare TNRs. The high PEC performance was attributed to the presence of NBF, which enhances the visible light absorption, but also to the large surface area of the interface, that provides efficient charge separation and high carrier mobility. Based on the analysis of experimental UV and visible optical response, electrochemical impedance spectroscopy, and chrono-amperometry, a microscopic mechanism was proposed to explain the observed activity of these systems.

Available in PDF, EPUB and Kindle. Book excerpt: There has been a resurgence of interest in light-induced water splitting as the search for storable carbon neutral energy becomes more urgent. Although the history of the basic idea dates back more than four decades, efficient, economical and stable integrated devices have yet to be realized. In the continuing quest for such devices, the field of photoelectrochemistry is entering a new phase where the extraordinary interdisciplinary of the research and development efforts are opening new avenues. This aspect of current research effort is reflected in the chapters of this book, which encompass present thinking in the various disciplines such as materials science, photo-electrochemistry and interfaces that can contribute to realization of viable solar fuel generators. This book presents a blend of the background science and recent advances in the field of photoelectrochemical water splitting, and includes aspects that point towards medium to long term future realization. The content of the book goes beyond the more traditional approaches to the subject by including topics such as novel excitation energy processes that have only been realized so far in advanced photonics. The comprehensive overview of current activities and development horizons provided by the impressive collection of internationally renowned authors therefore represents a unique reflection of current thinking regarding water splitting by light.
