Summary on Grant Application Form
The programme seeks to develop new hydrodynamic microelectrochemical reactors for applications in ESR spectroscopy that offer significant benefits over traditional insitu electrochemical esr technologies. The reactors will be constructed using microfabrication technology and optimised for specific chemical/analytical applications. The programme outlines the design, construction, quantification and application of these devices for insitu electrochemical e: analysis. The key benefits of the new cell designs include: rapid electrolysis of cell constituents, vast range of optimised experimental geometries feasible, du to flexibility of construction method, exhaustive electrochemical conversion of reagents within cells at high transport rates, excellent temperature control throughout the reactor, minute mixing regions for cells with multiple inlet designs, minute analysis volumes After preliminary characterisation studies the new technology will be used to examine the role of sigma radicals within electro reduction and oxidation processes, applied to the investigation of electrogenerated ionic liquids and the role of anion insertion and ionic salt formation and to examine the mechanistic pathways of photoelectrochemcially induced haldie expulsion reactions. Experimental studies will be augmented with numerical modelling which will permit quantitative analysis of the variation of electrolysis rat and esr signal intensity as a function of transport rate through the cell. Once validated the numerical models will act as a computer aided design tool to allow efficient design and implementation of the new flow through devices.
