P/Si-TiO₂ photocatalytic thick films on FTO glass substrates were prepared. TiO₂ thin films, as base layer, were first coated on substrates using a spin-coating technique. The slurry containing P/Si-TiO₂ nanoparticles was bar-coated on the surface of TiO₂ base layer, followed by calcining at 550 °C. The resultant films were characterized using x-ray diffractometer, scanning electron microscope, UV–Vis spectrophotometer, crosscut adhesion test, and recycling-use test. Under 365-nm UV-light irradiation, abilities of the films to photocatalytically degrade methylene blue were evaluated. The apparent rate laws obeyed 1st-order and the corresponding reaction rate constants (k′), based on the coated area of substrates, were estimated. k′ of the thick film (thickness: 6.5 μm; composition: P/Si-TiO₂ anatase crystallites with 16 nm average size) was 49.0 L/(m²-sub. h), which was about eight times of that of the thin film (k′ = 6.2 L/(m²-sub. h); thickness: 215 nm; composition: pure TiO₂ anatase crystallites with 8-nm average size).

在FTO玻璃基板上制备了P / Si-TiO ₂光催化厚膜。首先使用旋涂技术将TiO ₂薄膜作为基础层涂覆在基底上。将包含P / Si-TiO ₂纳米颗粒的浆料棒涂在TiO ₂基层的表面上，然后在550℃下煅烧。使用X射线衍射仪，扫描电子显微镜，UV-Vis分光光度计，横切粘合力测试和回收利用测试对所得膜进行表征。在365nm的紫外光照射下，评价了膜光催化降解亚甲基蓝的能力。表观速率定律服从一阶和相应的反应速率常数（k′），基于基材的涂覆面积，进行了估算。厚膜（厚度：6.5μm；组成：平均尺寸为16nm的P / Si-TiO ₂锐钛矿微晶）的k '为49.0L /（m ² -sub.h），约为膜的k '的8倍。薄膜（k ′＝ 6.2L /（m ² -h）；厚度：215nm；组成：平均尺寸为8nm的纯TiO ₂锐钛矿晶体）。
