A facile approach to the composition-controlled synthesis of monodisperse 2.2 nm AgPd alloy nanoparticles (NPs) is reported. The 2.2 nm AgPd NPs are highly active and durable catalysts for the dehydrogenation of formic acid. The study proves the unique approach in using alloying effects to enhance the catalytic activity of the NPs for hydrogen generation from formic acid (see picture).
