Sol-gel processing, chemical vapour deposition (CVD), plasma or flame spraying synthesis, hydro or solvo thermal syntheses, metal organic decomposition (MOD), laser pyrolysis, atomic or molecular condensation are some of the chemical processes based on transformations in solution to produce nanoparticles from atoms. These chemical processes rely on the availability of appropriate “metal-organic” molecules as precursors. Among the various precursors of metal oxides, namely metal b-diketonates and metal carboxylates, metal alkoxides are the most versatile. They are available for nearly all elements and cost-effective synthesis from cheap feedstock have been developed for some.
