摘要：A method for growing single-wall carbon nanotubes involves preparing acatalyst comprising catalytic metals, iron and molybdenum, and magnesium oxidesupport material and contacting the catalyst with a gaseous carbon-containing feedstockat a sufficient temperature and for a sufficient contact time to make single-wall carbonnanotubes. The weight ratio of iron and molybdenum can range from about 2 to 1 toabout 10 to 1 and the metals loading up to about 10 wt % of the MgO. The catalyst canbe sulfided. Methane is a suitable carbon-containing feedstock. The process can beconducted in batch, continuous or semi-continuous modes, in reactors, such as a
transport reactor, fluidized bed reactor, moving bed reactors and combinations thereof.The process also includes making single-wall carbon nanotubes with catalysts comprisingat least one Group VIB or Group VIIIB metal on supports such as magnesia, zirconia, silica,and alumina, where the catalyst is sulfided.
