The enhanced catalytic performance of the dumbbell NCs ( Au ( 0 . 80 ) Pd ( 0 . 20 ) - Fe ( x ) O ( y ) ) catalyst over that of the initial Au ( 0 . 75 ) Pd ( 0 . 25 ) NCs could be correlated to the presence of the epitaxial connection between the Fe ( x ) O ( y ) and the Au ( 0 . 80 ) Pd ( 0 . 20 ) domains ( as the main factor ) .
 Chemical: Au ( 0 . 80 ) Pd ( 0 . 20 ) - Fe ( x ) O ( y ); Chemical: Au ( 0 . 75 ) Pd ( 0 . 25 ); Chemical: Fe ( x ) O ( y ); Chemical: Au ( 0 . 80 ) Pd ( 0 . 20 )
