Improved bi-metallic nanocatalysts are manufactured using a control agent
to produce nanoparticles having a controlled crystal face exposure. The
bi-metallic nanocatalyst particles are manufactured in a two-step
process. In a first step, nanocatalyst particles are manufactured using
the control agent and the primary metal atoms. The primary metal atoms
and the control agent are reacted to form complexed metal atoms. The
complexed metal atoms are then allowed or caused to form nanoparticles.
The nanoparticles formed in the first step using the control agent have a
desired crystal face exposure. In a second step, the secondary metal
atoms are deposited on the surface of the primary metal nanoparticles.
The secondary catalyst atoms maintain the same crystal face exposure as
the primary metal nanoparticles.
