The support of powdered catalysts on mold bodies facilitates their handling and reusability. In case of photocatalytic applications, such as enhanced water purification processes, transparent supports with thin layers of the active material are desirable to obtain an optimal light efficiency. For the generation of such layers a precise control of layer thickness is crucial. Here, a multi‐step dip‐coating approach for the generation of TiO2 layers with varying thickness on glass rings is reported. Additionally, the coated glass rings were tested in the photocatalytic reduction of nitrate in aqueous solution under simulated sunlight.

通过浸涂生成的玻璃环上的 TiO2 层光催化还原硝酸盐

粉末状催化剂在模具主体上的支撑有利于其处理和可重复使用。在光催化应用中，例如增强水净化过程，需要具有活性材料薄层的透明载体以获得最佳光效率。对于此类层的生成，层厚度的精确控制至关重要。这里，一种用于生成 TiO2 的多步浸涂方法2据报道，玻璃环上的层具有不同的厚度。此外，还对镀膜玻璃环在模拟阳光下光催化还原水溶液中的硝酸盐进行了测试。
