Hollow spheres of Cu nanoparticles with an average diameter of 300-500 nm have been prepared by a simple reaction of CuCl and hydrazine in suspension in the presence of gelatin at 60 °C. Gelatin played a decisive role as an inhibitor of the direct attack of hydrazine on CuCl surfaces and in coagulation of the growing Cu producing the hollow spheres. The products were characterized by X-ray powder diffraction, transmission electron microscopy, UV-VIS absorption spectroscopy and X-ray photoelectron spectrometry.
