摘要
A heteroatom-containing nano-carbon material, based on the total weight of said heteroatom-containing nano-carbon material and calculated as the elements, has an oxygen content of 1-6 wt %, a nitrogen content of 0-2 wt %, a carbon content of 92-99 wt %. In its XPS, the ratio of the oxygen content as determined with the peak(s) in the range of 531.0-532.5 eV to the oxygen content as determined with the peak(s) in the range of 532.6-533.5 eV is 0.2-0.8; the ratio of the carbon content as determined with the peak(s) in the range of 288.6-288.8 eV to the carbon content as determined with the peak(s) in the range of 286.0-286.2 eV is 0.2-1; the ratio of the nitrogen content as determined with the peak(s) in the range of 398.5-400.1 eV to the total nitrogen content is 0.7-1. The heteroatom-containing nano-carbon material shows a good catalytic capability in dehydrogenation of hydrocarbons.
