Preparation of Amperometric Hydrogen-Phosphate Ion Sensor Based on Perovskite-Type Oxide Thick-Film by EPD Process

摘要: Perovskite-type structured LaCoO3 fine powder with high surface areas could be prepared by a polymer precursor method using acetylacetone (AcAc) as chelating agent at 500°C. This used for an electrophoretic deposition (EPD) process in acetylacetone-based suspension. The supported on carbon-cross device was the EPD without sintering process. showed good properties of amperometric sensing hydrogen-phosphate ion.
