Abstract: One-dimensional WO3 microrods are prepared via hydrothermal method and are used as template to prepare three-dimensional WO3/FeOOH composites by means of Fe3+ hydrolysis.The structure,composition and electrochemical properties of the composites are characterized by XRD,XPS,FESEM and electrochemical tests.The results show that WO3/FeOOH composites has excellent electrochemical performance and can be used as materials for supercapacitors.It has a specific capacity of 296.7 F·g-1 at a current density of 0.5 A·g-1,and a capacity of 171.7 F·g-1 at a current density of 10 A·g-1.Its specific capacity retention remains 92.3% after 1,000 cycles at a current density of 10 A·g-1.
