Surfactant effects on the synthesis of porous cerium oxide from a type IV deep eutectic solvent
In this work we present a novel, low temperature and green method for atom-efficient solvothermal synthesis of crystalline, micelle templated cerium IV oxide (ceria) from a type IV deep eutectic solvent (DES) comprising a hydrated cerium containing metal salt, cerium( iii ) nitrate hexahydrate (Ce(N...
