We report shape-controlled Pd nanoparticles (G-Pd NPs) synthesized by means of polyol process using glycerol as a reducing agent with poly(vinyl pyrrolidone) as a capping agent in aqueous solution. The G-Pd NPs consist of triangular and hexagonal plates and decahedron with dominant {111} facets confirmed by X-ray diffraction analysis and field-emission transmission electron microscopy. In cyclic voltammograms, the G-Pd NPs exhibit such an improved formic acid electrooxidation due to the metallic nanophases with the dominant {111} facets without any serious agglomeration in comparison with commercial Pd/C.
