Abstract:
1. A method for manufacturing a supported bi-metallic nanocatalyst having a controlled crystal face exposure, comprising, (i) preparing a solution comprised of a plurality of primary metal atoms composed of a first element and a plurality of control agent molecules and allowing the primary metal atoms and control agent molecules to react to form a complex; (ii) allowing or causing the complexed metal atoms to form a plurality of first nanoparticles composed of the primary metal atoms having a controlled crystal face exposure; (iii) thereafter depositing a plurality of secondary catalyst atoms composed of a second element that differs from the first element of the primary metal atoms on an outer surface of the first nanoparticles so as to form bimetallic nanoparticles composed of the first nanoparticles and the secondary catalyst atoms disposed on the outer surface of the first nanoparticles, the bimetallic nanoparticles having the same controlled crystal face exposure as the first nanoparticles; and (iv) supporting the nanoparticles on a support material.
