Nature is an inexhaustible source of ideas and materials. This time, chicken eggshell membrane, a nature product and waste material, has been discovered as a potential sulfur source for the production of sulfide. This is possible because of the presence of sulfur-containing amino acids in the proteins forming its fibers. In the present research eggshell membrane was high-energy ball milled with lead precursor to yield lead sulfide PbS, a semiconductor material suitable for the application in solar cells. Thus, a completely solid-state methodology (mechanochemical synthesis without the need to use toxic precursors and solvents and elevated temperatures has been successfully applied The effect of ratition speed and the type of lead precursor (acetate and nitrate) on the reaction course was investigated. The as-received powders were washed with distilled water, filtered and the content of lead in the filtrate reaction was measured by means of atomic absorption spectrometry. This provided a direct information about the reaction progress (reactants are water-soluble whereas the produced PbS is not.
