光催化剂已越来越多地应用于许多领域，并且期望增强其针对沉积在光催化剂层上的污垢物质的自清洁功能。在此，我们提出了纳米粒子的微印刷方法，使用二氧化钛纳米粒子悬浮液和硅橡胶印章制作微结构的光催化剂层。TiO 2纳米颗粒的烧结在600°C下进行，不会导致晶相从锐钛型转变为金红石型。我们通过生产微柱TiO 2阵列层来展示制造过程。由于硅橡胶印模是柔性的，所提出的技术有望适用于曲面上的微结构的制造。
Photocatalysts have been increasingly applied in many fields, and it is desirable to enhance their self-cleaning functions against fouling matter deposited on the photocatalyst layer. Herein, we propose the nanoparticle-microprinting method to fabricate a microstructured photocatalyst layer using a TiO2nanoparticle suspension and silicone rubber stamp. The sintering of TiO2nanoparticles was performed at 600°C without causing the crystal phase to change from anatase to rutile. We demonstrated the fabrication process by producing a micropillar TiO2array layer. Since the silicone rubber stamp is flexible, the proposed technique is expected to be applicable for the fabrication of microstructures on curved surfaces.
