Cu–Pd–B Alloy Nanoparticles Synthesized by External Boron Doping Method

Abstract We present a new synthetic approach for Cu–Pd–B nanoscale alloys. Crystalline face-centered cubic Cu–Pd–B alloy nanoparticles were successfully obtained via an amorphous structure phase caused by external heavy B doping. Elemental mapping with simultaneous energy-dispersive X-ray spectroscopy and energy loss spectroscopy in a scanning transmission electron microscope revealed a solid-solution structure composed of the three elements.
