Summary on Grant Application Form |
|
An electrochemical technique for the production of precursors to ceramic films on hydrogen-sorbing metal substrates will be investigated for a range of gas sensor applications. The technique used involves the electrolysis of aqueous non-dischargeable metal salt solutions, which yield hydrogen at the cathode, resulting in local generation of hydroxide ions at the electrode surface. Such conditions promote the precipitation of metal hydroxides and if the local alkaline environment is not disrupted by convective or other forces, then a solid phase accumulates at the cathode, and forms an adherent surface film. In order to maintain deposition, it is essential that gaseous hydrogen evolution is eliminated and this will be investigated by use of a hydrogen sorbing cathode material such as palladium or metal alloys. Calcination of the electrode and adherent film will yield a ceramic film. The generation of both porous and compact structures will be investigated, using various electrode potential cycling and pulsing regimes. The cermic films will be studied as the active components of humidity sensors. Apprpriate metal oxide films will be employed at elevated temperatures for the determination of fuel gases. Finally, ceramic/microparticulate platinum composite films will be investigated for applications in pellisters and as electrocatalytic systems.
