Chemical composition, particle size, and structure formation of colloidal Cu
2O and metallic Cu synthesized from Cu(II) acetate in an environmentally friendly 1,2-propane diol were studied dependent on the temperature and concentration of the precursor. Cu
2O as a reaction intermediate is formed between 150 and 170
°C, while its reduction to metallic Cu occurs between 170 and 180
°C. Average particle sizes of non-agglomerated Cu powders varied from 100
nm to 1
μm.
