Effects of chlorinated Pd precursors and preparation methods on properties and activity of Pd/TiO₂ catalysts.

ABSTRACT: We investigated the effects of Pd precursors and preparation methods on the physicochemical properties and performance of Pd/TiO₂ catalysts in the photocatalytic degradation of methyl violet. To confirm the influence of the precursors, Pd/TiO₂ catalysts were prepared via chemical reduction (CR) using four different Pd precursors. Additionally, to determine the effects of preparation methods, Pd/TiO₂ catalysts were fabricated using K₂PdCl₄ precursor via three different methods: CR, deposition-precipitation (DP), and impregnation. The CO chemisorption results showed that the catalyst prepared via DP using the K₂PdCl₄ precursor, i.e., Pd/TiO₂_K_DP, displayed the highest P
