Abstract
Nitrogen-doped carbon materials with well developed pore structure and high nitrogen content were prepared from cellulose and characterized by N2 adsorption,element analysis and X-ray photoelectron spectroscopy,then applied to SO2 removal.The role of nitrogen-containing groups in the desulfurization was studied by changing the calcination temperature and amount of urea.It is found that the nitrogen-containing groups,especially pyridine nitrogen,could effectively improve the activity of carbon materials towards SO2 removal.Such a result is closely related to the pyridine nitrogen enhancing SO2 adsorption and its oxidation to SO3.
