Heteroatom-Containing Nano-Carbon Materials, Methods and Applications for Their Preparation, and Dehydrogenation Methods for Hydrocarbons

摘要

The present invention provides a heteroatom-containing nano-carbon material, and a method for producing and using the heteroatom-containing nano-carbon material, wherein the content of oxygen is 1-6 wt% The content is 0-2 wt%, the carbon content is 92-99 wt%; In XPS, the ratio of the oxygen content measured at the peak (s) in the range of 531.0-532.5 eV and the oxygen content measured at the peak (s) in the range of 532.6-533.5 eV is 0.2-0.8; The ratio of the carbon content measured in peak (s) in the range 288.6-288.8 eV to the carbon content measured in peak (s) in the range 286.0-286.2 eV in spectroscopy is 0.2-1; The ratio of nitrogen to total nitrogen content measured at peak (s) in the range of 398.5-400.1 eV is 0.7-1. The heteroatom-containing nano-carbon material exhibits good catalytic performance in the dehydrogenation of hydrocarbons and can significantly increase the conversion of the starting material and the selectivity of the target product.
