Title

Ni–Co–Cu supported on pseudoboehmite-derived Al2O3: Highly efficient catalysts for the hydrogenation of organic functional groups

Language

English

Abstract

Ni-Co-Cu catalysts supported on pseudoboehmite-derived Al 2O 3 were developed for efficient hydrogenation of organic functional groups: CN and NO 2 associated with benzene as well as CC in butynediol. Factors such as thermo-treatment of pseudoboehmite, Ni loading, Cu and Co content, and catalyst operating parameters were systematically studied. Among the catalysts, 20%Ni-3%Cu-5%Co/Al 2O 3 performed the best, showing 100% feed conversion and 84-99.8% selectivity of target products. Techniques such as N 2 sorption measurement, scanning electron microscope, hydrogen temperature-programmed reduction and desorption, X-ray photoelectron spectroscopy, and in situ X-ray diffraction were used to characterize the catalysts. The superior performance of the catalyst can be attributed to synergetic interaction among the Ni-Cu-Co constitutes as well as enhancement of Ni 2+ reduction and Ni 0 dispersion that are resulted due to the co-presence of Cu and Co. © 2012 Elsevier B.V.
