Bimetallic PdAu catalysts for formic acid dehydrogenation

A series of monometallic and bimetallic palladium gold catalyst were prepared and studied for the formic acid dehydrogenation reaction. Different Pd/Au compositions were employed (PdAu, where x = 25; 50 and 75) and their impact on alloy structure, particle size and dispersion was evaluated. Active p...
