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 layer
was detected for 1.9 wt.%. The fresh and used catalysts were characterized by SEM, EDS, XRD and XPS.
