摘要:

采用电喷雾离子化沉积技术, 在氟掺杂锡氧化物(FTO)衬底上制备了均匀的无定形铁镍双金属氢氧化物薄膜. 与浸泡法制备的薄膜相比, 该薄膜具有更高的纯度、 更大的比表面积和较高的电催化水氧化性能, 在10 mA/cm 2时的过电位为290 mV, 并在催化反应中表现出良好的稳定性, 为可控合成高催化活性的过渡金属氢氧化物薄膜提供了一种新方法.

Abstract:

Electrospray ionization technology is an efficient method for the synthesis of high purity thin film materials. Uniform amorphous Fe-Ni bimetallic hydroxide films were prepared on FTO substrate by electrospray ionization deposition. Compared with the films prepared by immersion method, the films prepared by electrospray deposition exhibit higher purity and larger specific surface area. The Fe-Ni bimetallic hydroxide films performs high electrocatalytic water oxidation property, the overpotential at 10 mA/cm 2 is 290 mV. Meanwhile, the film shows excellent stability in the catalytic reaction. This study provides a new method for the controllable synthesis of transition metal hydroxide films with high catalytic activity.

Key words: Electrospray ionization, Bimetallic hydroxides, Electrocatalytic water oxidation
