Zinc oxide (ZnO) nanoparticles (NPs) were synthesized on a fluorine-doped tin oxide (FTO) substrate by sol–gel coating and hydrothermal method to produce a film with self-cleaning and transmittance properties. To improve hydrophilic and photocatalytic activity of the film, zinc oxide titanium dioxide (ZnO@TiO₂) core–shell NPs were synthesized using two different amounts of TiO₂. The ZnO@TiO₂ array film showed better stability and transmittance than the ZnO array film. The hydrophilicity of the ZnO@TiO₂ array film was better, because its contact angle was smaller than that of ZnO array film. The wettability also increased with increasing TiO₂ concentration. In addition, the ZnO@TiO₂ core–shell NP array FTO film exhibited excellent photocatalytic activity in comparison with the ZnO array film. This study demonstrates that the ZnO@TiO₂ core–shell NPs array FTO film is more useful due to its self-cleaning and transmittance properties.

通过溶胶-凝胶涂覆和水热法在掺氟氧化锡（FTO）基底上合成了氧化锌（ZnO）纳米颗粒（NPs），以生产具有自清洁和透射特性的薄膜。为了提高膜的亲水性和光催化活性，使用两种不同量的TiO ₂合成了氧化锌二氧化钛（ZnO @ TiO ₂）核-壳NP 。ZnO @ TiO ₂阵列膜显示出比ZnO阵列膜更好的稳定性和透射率。ZnO @ TiO ₂阵列膜的亲水性更好，因为其接触角小于ZnO阵列膜。湿润性也随着TiO ₂浓度的增加而增加。另外，ZnO @ TiO ₂与ZnO阵列膜相比，核-壳NP阵列FTO膜表现出优异的光催化活性。这项研究表明，由于ZnO @ TiO ₂核壳NPs阵列FTO膜具有自清洁和透射特性，因此更加有用。
