Site‐selective electrodeposition of catalytically active metals on electrically conducting support particles was achieved by polarization with an electric field in a nonconductive matrix in the presence of metal salt solutions. The transmission electron micrograph shows a graphite particle to which Pd and Au were applied sequentially to opposite ends by reversing the direction of the electric field.
