Abstract: AuPd alloyed nanoparticles are regarded as very active catalysts for oxidation of alcohols. However we found that their catalytic activity can be further improved after calcination in air, which lead to the restructuring of alloyed AuPd nanoparticles and PdO segregation on the surface. The alloyed character was partially recovered upon reduction with H2 atmosphere, but the yet Pd-rich surface was less active in the oxidation of the model molecule benzyl alcohol.
