Outline of Final Research Achievements

In this study, we have developed solvent free synthesis of organic inorganic hybrid nanoparticle by thermal decomposition of alkyl amine coordinated metal oxalate complex. At first, alkylamine coordinated metal oxalate complex with various metal ions were prepared. The properties of alkylamine coordinated metal oxalate, such as melting point and thermal decomposition temperature, were measured. Various monodiperse organic-inorganic hybrid nanoparticles, such as silver, copper, and iron oxide, were synthesized bay thermal decomposition of alkylamine coordinated metal oxalate complex without using any solvents.
