Resumen:
Pd catalysts supported on activated carbon felts (ACFs) with different metallic loadings were prepared by electroless plating and evaluated for the reduction of nitrite in water in a batch reactor. Homogeneous Pd dispersions were obtained, the plating solution concentration and the seeding step being the key variables that determine particle size and morphology. The formation of Pd crystals of 96±22 nm situated at the external surface of the carbon fibers was obtained for 0.14 wt.% of metal loading, while an incipient formation of a Pd thin layerwas detected for 1.9 wt.%. The fresh and used catalysts were characterized by SEM, EDS, XRD and XPS.fibers was obtained for 0.14 wt.% of metal loading, while an incipient formation of a Pd thin layerwas detected for 1.9 wt.%.
