Fabrication of homogeneously distributed (HD) macropores by breath figure process is an active research area. Adopting the process, for the first time, we report the fabrication of HD macro with nested meso (hierarchical) porous nanocrystalline zinc indium oxide conducting sol-gel thin film on glass by dip-coating at 45-50% room relative humidity (RH) from a solution in ethanol-2-butanol (1:1, w/w) medium with a 1:1, Zn:In ratio. In this process, solution composition and RH are found to play key roles on HD macropore generation. The film is highly promising toward visible-light-driven photoelectrochemical water splitting.
通过呼吸图形工艺制造均匀分布（HD）大孔是一个活跃的研究领域。我们首次采用该工艺，通过在室温相对湿度（RH）为 45-50%的乙醇-2-丁醇（1:1，w/w）介质中的溶液中以 45-50%的室温相对湿度（RH）进行浸涂，在玻璃上制备了具有嵌套介孔（分级）多孔纳米晶氧化锌铟导电溶胶-凝胶薄膜的 HD 大孔，Zn:In 比为 1:1。在这个过程中，发现溶液组成和 RH 对 HD 大孔的生成起着关键作用。该薄膜在可见光驱动的光电化学水分解方面具有很大的应用前景。
