摘要

采用旋涂法在导电玻璃(FTO)上制备了CuBi_2O_4薄膜。通过调控旋涂的次数,得到具有较优光电化学性能的CuBi_2O_4薄膜。同时研究了多次旋涂过程中旋涂转速、烘干温度对制备的薄膜的均匀性的影响。实验结果表明:采用3 000 r/min转速,300℃的烘干温度可以得到均匀的薄膜。旋涂层数为4层时可以得到最优的光电催化性能,较旋涂3次的薄膜性能提升72%。
        CuBi_2O_4 thin film was deposited on FTO substrate by the spin coating method. The CuBi_2O_4 thin film with optimal photocatalytic performance was obtain by adjusting the number of spinning. Meanwhile, the influences of rotary speed and baking temperature on the uniformity of thin film during the repeated spinning process was studied. The results showed that CuBi_2O_4 film prepared with 3000 rpm rotary speed and 300 ℃ baking temperature had the best thin film uniformity, and the optimal photoelectrochemical performance was obtained when the spin coating was repeated 4 times, corresponding to 72% enhancement compared to that of thin film with spin coating of 3 times.
