摘要：
We report a nanocarbon material with nanodiamond（ND） core and graphene shell（ND@G） as a support for Pd nanocatalysts. The designed catalyst performed good selectivity of styrene（85.2%） at full conversion of phenylacetylene and superior stability under mild conditions. Supported Pd catalysts are characterized by means of high resolution transmission electron microscopy（HRTEM）, Raman, X-ray diffraction（XRD）, X-ray photoelectron spectroscopy（XPS） and H;temperature-programmed reduction（H;-TPR）.The results clearly show that formation of the strong metal-support interaction（SMSI） between Pd nanoclusters and the defective graphene shell helpfully modifies the selectivity and stability of the Pd-based catalysts.
