Elemental sulfur nanoparticles (nanosulfur, S 0 ) have been obtained in a matrix consisting of sodium sulfite (diluent and a final reaction product) and succinic acid (catalyst) by mechanochemical syntheses via the reaction Na2S2O3 · 5H2O + H2(C4H4O4) + zNa2SO3 = (z + 1)Na2SO3 + H2(C4H4O4) + 5H2O+ S 0 , at z = 19.6. It has been shown that free nanodispersed sulfur can be obtained by dissolving the matrix in water. The prepared samples have been characterized using a set of physical and physicochemical methods.
