摘要：
本工作以两步水热法成功制备了三维立体结构的WO3/CuWO4复合薄膜，通过调整CuWO4的水热时间得到了复合薄膜的最佳制备条件，并对WO3/CuWO4复合薄膜进行吸收光谱测试、光电流测试、光电催化测试和电化学阻抗测试。结果表明，所制备的WO3/CuWO4-5 h复合薄膜的带隙介于CuWO4和WO3之间，为2.44 eV,具有更宽的光谱响应范围；在1.5 V的偏压下，WO3/CuWO4-5 h复合薄膜表现出2.11 mA/cm2的高光电流密度；WO3/CuWO4-5 h复合薄膜对亚甲基蓝溶液的光电催化降解效率为58.5%,高于WO3薄膜（降解效率为41.4%）;电化学阻抗谱表明，WO3/CuWO4薄膜电荷转移电阻比单一WO3薄膜小，对应更好的光电化学性能。
