摘要: Ru catalysts supported on three types of graphite nanofiber materials, stacked-cup (PR24-HHT), platelet (CNF-P) and bamboo-like (CNF-B), have been synthesized characterized by HRTEM calorimetry CO adsorption. The influence the support nanostructure their catalytic performance in selective hydrogenation paracetamol was also studied. An inverse correlation between heats adsorption activity stereoselectivity to trans-4-acetamidocyclohexanol found. results rationalized terms morphology electronic properties metal particles. These features are controlled different location crystallites metal-support interactions induced that eventually depend support. As a consequence supports seem modify nanoparticles surface structures, shift selectivities can be related with variations reactant chemisorption over such surfaces.
