Abstract
The modifications of support for the dispersion and immobilization of gold nanoparticles were examined for the selective hydrogenation of acetylene to ethylene. The catalyst, denoted as Au/CNA, was prepared by the carbonization of C and N atom-containing organic precursors on Al2O3, which were subsequently used as supports for gold nanoparticles. The TOF value of Au/CNA was five times higher than that of Au/Al2O3 at 250 °C. The carbonization modification of Al2O3 support without N species showed almost no change in catalytic activity. Therefore, the improved catalytic performance of Au/CNA is related to the interactions of the N species on the CNA support with nano-gold particles. From the XPS analysis, electron transfer between gold and C, N co-doped species may play an important role in the high levels of Au active site utilization. This study may provide new avenues for the construction of organic/inorganic composite materials for efficient catalytic hydrogenation applications.
