Abstract

A co-solvent assisted spray pyrolysis process was developed for the formation of pure metal particles from metal salt precursors without the direct addition of hydrogen or other reducing gas. Generation of pure copper and nickelparticles from aqueous solutions of copper acetate, copper nitrate, and nickel nitrates over the temperature range of 450 C difference} 1000 C was demonstrated. Addition of ethanol as a co-solvent plays a crucial role in producing pure metal powders. Results of a modeling study of ethanol decomposition kinetics suggest that co-solvent decomposition creates a strong reducing atmosphere during spray pyrolysis via in-situ production of hydrogen and carbon monoxide.
