Investigation of structural optical and electronic properties of zirconia based nanoceramic materials prepared by sonochemical method

Abstract

newlineThe present research work aims to establish a new class of newlineadvanced nanoceramic solid ion conducting materials for possible application newlinein SOFC as electrolyte There are two major groups of solid ion conducting newlinematerials namely fluorite structured materials that are oxygen ion conductors newlineand perovskite structured materials that are proton conductors Research has newlinebeen focused on such group of materials and directed towards synthesis and newlinecharacterization of these materials with special interest in scaling down the newlineparticle size to nanolevel and designing different morphological architectures newlineThis new class of materials with nanometric size and better newlinemorphology has been taken up as the main interest as it is a challenging and newlinevital research currently for development and commercialization of SOFC that newlinewill enable green renewable energy source in near future The increasing newlineenergy demand and depletion of fossil fuel has forced the search of new newlinerenewable energy sources One such advantageous renewable energy source is newlineSOFC that still lacks material research inorder to overcome the technical newlinechallenges faced for successful fuel cell operation and its commercialization newlineState of the art of nanotechnology remarks a great potential for newlineSOFC The concept of super ionic conduction in nanomaterials and newlinenanocomposites with different architectures especially 1 dimensional newlinenanostructures can overcome SOFC challenges by enhancing ionic newlineconductivity and ion transport in grain boundaries through continuous newlinechannels in interfaces at significantly low temperature At nanoscale, ionic newlineconduction at grain boundary becomes a positive factor by promoting ion newlinemigration through network of channels at interface of nanoparticles Therefore newlineto achieve super ionic conduction it is necessary to concentrate on synthesis of newlinenanostructures of solid state ion conducting material newline newline
