Electrophoretic deposition (EPD) was applied for the coating of a Pd/TiO₂ catalyst for the production of biohydrogenated diesel (BHD) in a microscale-based reactor. The coating of TiO₂ using EPD was investigated under various operating conditions. The Pd/TiO₂ catalysts prepared by EPD were compared with the samples obtained by the conventional washcoating (WC) technique. The optimum EPD condition giving a high degree of adhesion was determined, using Tiron and Pluronic F127 as the additives. The coated catalysts were tested for their catalytic activity. By comparing with Pd/TiO₂(WC), Pd/TiO₂(EPD) catalysts exhibited a higher catalytic performance which could be explained by their uniformity, high amount of Ti³⁺ species, and oxygen vacancies.

通过电泳沉积在微型反应器中包覆 Pd/TiO2 用于生物氢化柴油生产

应用电泳沉积 (EPD) 涂覆 Pd/TiO ₂催化剂，用于在微型反应器中生产生物氢化柴油 (BHD)。在各种操作条件下研究了使用 EPD的 TiO ₂涂层。将通过 EPD 制备的 Pd/TiO ₂催化剂与通过常规修补基面涂层 (WC) 技术获得的样品进行比较。使用 Tiron 和 Pluronic F127 作为添加剂，确定了具有高度粘附性的最佳 EPD 条件。测试涂覆的催化剂的催化活性。通过与 Pd/TiO ₂ (WC) 相比，Pd/TiO ₂(EPD) 催化剂表现出更高的催化性能，这可以通过它们的均匀性、大量的 Ti ³⁺物种和氧空位来解释。
