A two-step synthesis for the preparation of single-phase and nanoparticulate GaPd and GaPd2 by coreduction of ionic metal-precursors is described. The nanoparticles have been characterized by XRD, aberration-corrected TEM, and chemical analysis to ensure the formation of the intermetallic compounds. The nanoparticles possess high catalytic activity while maintaining the excellent selectivity of the ground bulk materials in the semihydrogenation of acetylene.
