ORION puts together a multidisciplinary consortium of leading European universities, research institutes and industries with the overall goal of advancing the fabrication of inorganic-organic hybrid materials using ionic liquids. Maximum research efforts within ORION will be addressed to achieve inorganic-organic hybrids with an ordered nanostructure and to understand and characterize the new generation of inorganic-organic hybrids. ORION aims to take advantage of the properties of Ionic Liquids as templating supramolecular solvents in the synthesis of novel hybrid materials. Additionally, the use of ILs will bring innovative properties to the hybrid materials due to their intrinsic wide electrochemical window and high ionic conductivity and hence this method will generate radically new materials. The new ordered inorganic-organic hybrids will be morphologically and electrochemically characterized with emphasis on their potential application in batteries, innovative solar cells and gas sensors. By reaching this ambitious goal, ORION will pave the way towards inorganic-organic hybrid products for chemical, materials, energy and sensor industries.
