23. (Photo)electrochemical Water Oxidation: From Catalysis to Functional Device
Abstract : The key challenge within artificial photosynthesis is achieving efficient electro- or photo-driven water oxidation catalysis, a necessary process to supply the protons for the reduction reactions, thereby enabling solar fuel production. To facilitate efficient water (photo)electrolysis for solar fuel production, this thesis focuses on two aspects: 1) elucidating the O-O bond formation mechanism and developing efficient, stable, and economical water oxidation catalysts (WOCs); 2) exploring stable, low-cost, light-absorbing photoanode materials that have suitable band structures and excellent charge diffusion properties.

24. Electrochemistry, photoelectrochemistry and photoelectron spectroscopy of nanostructured metal oxides
Abstract : Dye-sensitized nanostructured metal oxides are promising materials for solar energy conversion in photoelectrochemical solar cells. For nanostructured TiO2 electrodes, photocurrents were used to study the electron transport. In both steady state and time resolved measurements, the photocurrents could be described by diffusion of electrons. READ MORE

25. Microbial Electrochemical System: extracellular electron transfer from photosynthesis and respiration to electrode
Abstract : The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to electrodes is restricted due to the insulated cellular exterior made of lipid structures. READ MORE
