The in situ DRIFT-CO and XPS data demonstrated that the mild oxidation of PdIn intermetallic nanoparticles results in the partial oxidation of an In component and the trans-formation of isolated Pd1 sites to Pdn multiatomic ones thus enhancing PdIn activity in the liquid-phase hydrogenation of diphenylacetylene without sacrificing the alkene selectivity.
