Synthesis of Copper Nanoplates by Reduction of Cu(II) in the Presence of an Alkoxycarboxylic Acid

Triangular and hexagonal copper nanoplates were synthesized by reduction of copper(II) nitrate with hydrazine hydrate in water in the presence of 2-[2-(2-methoxyethoxy)ethoxy]acetic acid. The resultant copper particles were characterized by X-ray diffraction analysis and electron microscopy. The effect of the synthesis temperature and duration, as well as of the stabilizer, copper ions, and sodium hydroxide concentrations on the size, morphology, and polydispersity degree of the particles synthesized was evaluated.
