综述了利用电化学阳极氧化和阴极电沉积两种电化学途径合成用于光电化学水分解的纳米wo3薄膜的研究进展。阐述了电化学阳极氧化法和阴极电沉积法合成纳米wo3薄膜的关键基本反应机理。此外，还详细阐述了金属氧化物前驱体、电极衬底、外加电位和电流密度以及退火温度对电化学合成的纳米wo3薄膜的尺寸、组成和厚度的影响。最后，总结了用于计算纳米结构wo3薄膜能量转换效率的一般评估实践，并提出了规范该领域研究结果的建议，以便在不久的将来容易比较报道的PEC效率。
The recent developments of nanostructured WO3thin films synthesized through the electrochemical route of electrochemical anodization and cathodic electrodeposition for the application in photoelectrochemical (PEC) water splitting are reviewed. The key fundamental reaction mechanisms of electrochemical anodization and cathodic electrodeposition methods for synthesizing nanostructured WO3thin films are explained. In addition, the effects of metal oxide precursors, electrode substrates, applied potentials and current densities, and annealing temperatures on size, composition, and thickness of the electrochemically synthesized nanostructured WO3thin films are elucidated in detail. Finally, a summary is given for the general evaluation practices used to calculate the energy conversion efficiency of nanostructured WO3thin films and a recommendation is provided to standardize the presentation of research results in the field to allow for easy comparison of reported PEC efficiencies in the near future.
