Sol-Gel Synthesis and Characterization of Co-Mo/Silica Catalysts for Single-Walled Carbon Nanotube Production

摘要

Previous studies by our group [1-3] have demonstrated that Co-Mo/silica catalysts exhibit high selectivity to the growth of single-walled carbon nanotubes (SWNT) by CO disproportionation. The effect of parameters such as the extent of interaction of different Co-Mo species with the support, metal loading, Co:Mo molar ratio, and reaction conditions on the yield and structural properties of SWNT were analyzed. In this context, the present study focuses on the potential effects in the Co:Mo interaction using different supports.
