N2 - Partial hydrogenation of 1,3-butadiene (C4H6) to butene (C4H8) on hydrogen precovered Pd (110) has been investigated using temperature-programmed desorption (TPD), scanning tunneling microscopy (STM) and high resolution electron energy loss spectroscopy (HREELS). Below room temperature, C4H6 was molecularly chemisorbed on a hydrogen precovered Pd(110) surface, and was in n-bonded chemisorption states. The hydrogenation of C4H6 did not occur in the sparse domains less than 0.25 ML (c(4×2)). With increasing the C 4H6 coverage, C4H6 formed dense domains and the π-bond was weakened. Only the weakly π-bonded C 4H8 was hydrogenated to C4H8 at about 200 K. We propose that c(4 × 2) structure of 1,3-butadiene acts as the template for the activation of hydrogenation.
