Abstract

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.
