The process of the ligand release and the reduction of [Pd(NH<SUB>3</SUB>)<SUB>4</SUB>]-form sulfonic resin has been studied by chemical analysis, X-ray photoelectron spectroscopy and adsorption techniques. The removal of ammonia ligands remarkably increased with hydrogen treatment above 353 K, and was complete at around 393 K. It is suggested that the released ammonia partly transfers to –SO<SUB>3</SUB><SUP>−</SUP> groups to form –SO<SUB>3</SUB>NH<SUB>4</SUB> groups as the reduction proceeds. The dispersion of the metal particles prepared by hydrogen reduction ranged from 0.11 to 0.31 depending on the loading concentration of the palladium cation. The metal particles are considered to be entrapped in the pores of the resin. The formation of cationic palladium sites by the low temperature reduction is also suggested.
