Work in Progress
• “Localized Study of the Surface Passivation and Recovery on a substoichiometric TiO2 Material using Scanning Electrochemical Microscopy”
Status: Manuscript in preparation
Abstract: Substoichiometric TiO2 has been deemed as one of most promising electrode materials used in electrochemical advanced oxidation processes, due to its ability to produce hydroxyl radicals from water oxidation and low cost. It, however, suffers from gradual conductivity deterioration, known as surface passivation, as a result of oxygen-reinsertion into the lattice structure during long term anodic polarization. In this study, a novel substoichiometric TiO2 disk membrane was synthesized in a thermal reduction process, and the surface passivation and recovery were examined in various electrolyte solutions by electrochemical methods and X-ray diffraction (XRD). Scanning electrochemical microscopy was employed to provide spatial visualization of both phenomena, and measure local kinetic change through the charge transfer of a redox reaction, while XRD was used to identify the phase change of this crystalline material. Results of this study provided a great understanding of the surface passivation and recovery on the substoichiometric TiO2 material, and are fundamental to develop the electrode material with long term stability.
• “Localized Study of the Long-Term Stability of a Fluorinated Boron Doped Diamond Electrode using Scanning Electrochemical Microscopy”
Status: Data collection in progress
Abstract: The use of boron doped diamond (BDD) electrodes is limited by the formation of perchlorate when they are used during the electrolysis of chloride-containing water, since perchlorate is difficult to remove and responsible for the disruption of the endocrine and reproductive systems. Fluorinated BDD using silanization method has exhibited great potential in limiting the formation of perchlorate without affecting the rates of organic compound oxidation significantly, however, this fluorinated BDD suffers from long-term stability under anodic polarization, and therefore loses its functionality eventually. In this study, the long-term stability of fluorinated BDD was examined by several electrochemical methods, X-ray photoelectron spectroscopy (XPS) and Energy-dispersive X-ray spectroscopy (EDS). Scanning electrochemical microscopy was adopted to visually and locally resolve the stability through the charge transfers between redox couples of different charges (positive, neutral and negative). Cyclic voltammetry was used to investigate changes in the electrochemical response for the bulk surface. The changes to the electrode surface functional groups and surface elements were examined by XPS and EDS. Results of this study provided a fundamental understanding of the long-term stability of fluorinated BDD using silanization method.
