PHOTOELECTROCATALYSIS Preparation of photocatalytic materials (TiO2, WO3) by electrosynthesis/electrodeposition methods. Characterisation of photocatalytic materials by microscopic and spectroscopic techniques. Electrically enhanced photocatalysis (photoelectrocatalysis) at TiO2 and WO3 plain or composite electrodes for the photo-oxidation of organic contaminants. ELECTROANALYSIS Fabrication of microelectrodes and design of electrochemical detectors and sensors. Microelectrodes in electrochemical HPLC detection. Stripping voltammetry at Bi-coated micro- and macro-electrodes. Solid polymer amperometric gas sensors. MISCELANEOUS Adsorption at charged interfaces (polarized Hg electrode). Mechanistic studies using microelectrodes. Corrosion at microelectrodes. Scanning probe microscopies (AFM, STM, SECM).
