采用水热法制备一维WO₃微米棒，并以其为模板利用Fe³⁺水解成功制备出具有三维结构的WO₃/FeOOH复合材料。利用X射线衍射（XRD）、X射线光电子能谱仪（XPS）、场发射扫描电子显微镜（FESEM）、电化学测试等手段对材料的结构、组成以及电化学性能进行了表征。结果表明，WO₃/FeOOH复合材料作为超级电容器材料具有优异的电化学性能。电流密度为0.5 A/g时，比容量高达296.7 F/g；电流密度为10 A/g时，比容量为171.7 F/g。并且在电流密度为10 A/g时循环1 000次后，其比容量保持率为92.3%。

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.
