We present a facile solution‐phase method for the synthesis of Cu2S microcrystals with rod‐like morphologies by the reaction of sulfur with three‐dimensional substrate copper foam in a mixed solvent of ethylene glycol and deionized water. The lengths of Cu2S microrods are between 80 and 150 μm and the diameter is among 3 to 8 μm. Monodisperse Cu2S microrods self‐assemble into echinus structure. The samples were characterized by X‐ray powder diffraction and scanning electron microscopy. Energy dispersive X‐ray spectroscopy was further used to testifiy the purity of Cu2S. Catalysis performance proved that the obtained Cu2S materials possess superior catalytic efficiency on methylene blue with the assistance of H2O2. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
