One dimensional CoMoO4 nanorods with monoclinic crystal structure are successfully fabricated by a facile chemical co-precipitation method. The CoMoO4 nanorods synthesized at 70 degrees C exhibit excellent supercapacitive performance. A high specific capacitance of 286 F g(-1) is achieved at a current density of 5 mA cm(-2) and 97.5% of the initial specific capacitance is remained after 2000 cycles. The excellent stability is mainly due to the stable crystal structure and good structure stability of one dimension CoMoO4 nanorods. This study puts forward a new research strategy for developing and using of binary metal oxides based new electrode materials in electrochemical capacitors. (C) 2012 Elsevier B.V.
