Pd-PANI: preparation and catalytic properties

PANI base was doped in PdCl2 aqueous solutions of low acidity containing pr edominantly electrically neutral [PdCl2(H2O)(2)] complexes. Under these con ditions partial (80%) reduction of Pd2+ to Pd-0 took place. Pd-0 created in this way was present in the form of crystalline particles (XRD, SEM). Pd-P ANI exhibited catalytic activity in the liquid phase 2-ethylanthraquinone h ydrogenation. The rate and the selectivity of hydrogenation depended on the Pd-0 amount in catalysts.
