Nitrogen-doped mesoporous carbon materials for oxidative dehydrogenation of propane

The CN-15-x series materials with different doses of SBA-15 template and the CN-y-2.0 series materials with different hard templates were prepared by the hard template method with hexamethylenetetramine as the carbon and nitrogen source. The obtained mesoporous carbon materials were characterized by X-ray diffraction (XRD),N(2)adsorption-desorption, transmission electron microscopy (TEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The catalytic performance of propane oxidative dehydrogenation was determined. The characterization results indicate that the catalytic activity of CN-15-2.0 with a bipartite hexagonal ordered structure was higher than those of the other materials. The conversion of propane was 22.98%, and the selectivity toward propylene was 41.70%.
