| Abstract Scope |
Inorganic pigments can be superior to organic pigments with respect to resistance to oxidative deterioration, fading when exposed to sunlight, and, in some cases, toxicity. It was discovered in this investigation that green pigments could be prepared by the pyrolysis of low-temperature single source precursors. The latter were prepared by precipitation of a solid solution of mixed zinc and cobalt salts of 2-oximinopropionate containing 5 to 10% of cobalt versus zinc. These complexes decompose at low temperature in the solid state to produce fine powders of metal oxides with the simultaneous release of acetonitrile, carbon dioxide, and water. The cobalt-doped zinc oxide produced in this matter is a dark green in color. Beyond use as a pigment, this material can also be applied as a bactericidal agent to control water borne bacterial pathogens and as a photocatalyst for the degradation of methylene blue dye in aqueous medium. |
