This dissertation presents surface enhanced photoanodes and oxygen evolution reaction (OER) catalysts for solar water splitting to produce hydrogen. The enhancement could be achieved by either introduced surface plasmon enhanced metallic nanostructures, such as Au or Ag nanoparticles, or adjusted surface structure, chemical composition and band structure of TiO2. This dissertation also presents various electrochemical and spectroscopic techniques used to characterize nanostructured materials for solar water splitting reactions. Firstly, a model photoanode comprised of [email protected] core-shell nanoparticles (NPs) on a nanostructured TiO2 substrate is presented for visible light sensitive photoelectrochemical properties. The nanostructured electrode is coated with TiO2 nanowires (NW) on Ti plate to provide a high surface area for efficient light absorption and efficient charge collection from [email protected] NPs. Pronounced photoelectrochemical responses of [email protected] NPs under visible light responses were obtained. These responses were attributed to collective contributions of local surface plasmon enhancement, enhanced charge collection by [email protected] NWs, and high surface area of the nanostructured electrode system. The shell thickness and core size of the [email protected] core-shell structure can be controlled and the optimal photoelectrochemical performance with a core size of 17 nm (in diameter) and shell thickness of 8 nm was formed. Secondly, a [email protected]/[email protected] nanostructured photoanode was prepared by decorating a CdS thin film layer onto a Au/[email protected] NWs substrate. Compared to CdS/[email protected] NWs photoanode, [email protected]/[email protected] exhibits a significant enhancement to water splitting efficiency. iii The enhanced photoelectrochemical catalytic activity is attributed to the surface plasmon enhancement of Au nanoparticles. XPS, XRD, SEM, EDS, high resolution TEM, AC impedance and other electrochemical methods were applied to resolve the structure-function relationship of the nanostructures of [email protected]/[email protected] NWs and [email protected]/[email protected] NWs electrodes. The studies of the photocatalytic activity of the core-shell structure, as well as a core-shell structure predictive model can further improve the understanding of the interplay between the shell thickness and core size and guide the design of highly efficient core-shell materials. Lastly, chapter 5 of this dissertation presents a high efficiency, durable, and low-cost oxygen evolution reaction (OER) catalyst based on earth-abundant elements, carbon, oxygen, and titanium for renewable energy conversion and storage devices. In this study, we report a highly active nanostructured electrode NanoCOT (C, O and Ti) for an efficient OER in alkaline solution. The NanoCOT electrode is synthesized from the carbon transformation of nanostructured TiO2 in an atmosphere of methane, hydrogen and nitrogen by a CVD process. The NanoCOT exhibits highly enhanced OER catalytic activity in alkaline solution, providing a current density of 1.33 mA/cm2 at an overpotential of 0.42 V, which is about 4 times higher than an IrO2 electrode and 15 times higher than a Pt electrode because of its nanostructured high surface area and favorable OER kinetics. The enhanced OER catalytic activity of NanoCOT is attributed to the presence of a continuous energy band of the titanium oxide electrode with predominantly reduced defect states of Ti (e.g., Ti1+, Ti2+ and Ti3+) formed by chemical reduction with hydrogen and carbon. OER performance of NanoCOT can also be further enhanced by decreasing its overpotential 150 mV at a current density of 1.0 mA/cm2 after coating its surface electrophoretically with 2.0 nm IrOx nanoparticles (NPs).

Current concerns regarding greenhouse gas-related environmental effects, energy security, and the rising costs of fossil fuel-based energy has renewed interest in solar energy in general and photovotaics in particular. Exploring state-of-the-art developments from a practical point of view, Nanotechnology for Photovoltaics examines issues in increasing efficiency, decreasing costs, and how these two goals can be achieved in a single photovoltaic device. It provides fundamental background and places research approaches within the proper physical context as related to photovoltaics performance enhancement. The book reviews the applications of devices and their performance requirements, followed by coverage of thin films and advanced band structure concepts for obtaining efficiencies above the Shockley–Queisser single bandgap efficiency limit of ~31%. The editor and contributors also discuss the basic optical properties of nanostructured materials as related to photovoltaics applications and describes nanoscale optoelectronic device physics related to performance. They then explore recent literature in the application of various classes of nanostructures to photovoltaics. The book covers solar cells based on hybrid organic-inorganic nanocomposites structures, quantum wells, nanowires/tubes, and quantum dots. It also discusses the use of nanoparticles/quantum dots to enhance the performance of conventional solar cells and luminescent solar concentrators. Each chapter summarizes the historical development for the nanostructure class under consideration, applications beyond photovoltaics, and the major synthetic methods, followed by a critique of leading works that have employed the particular nanostructure type. The book examines the advantages of each nanostructure approach and the remaining technical challenges, with an emphasis on possible future areas of research interest. It concludes with a summary of the major processing approaches and challenges of using the various nanostructures to photovoltaics applications, focusing on future scale-up and nanomanufactuting issues. Many books cover photovoltaics and many others nanotechnology — it is the coverage of both in one resource that sets this book apart.
