Preparation of Sulfur-Doped Porous Carbon Using Potassium 6-Hydroxy-2-Naphthalene Sulfonate as Activator
Sulfur-doped porous carbon has shown great potential in many aspects due to its excellent physical and chemical properties.This article proposes the direct synthesis of sulfur-doped porous carbon(SDPC)using glucose as raw material,which is widely sourced,cost-effective,and environmentally friendly,and potassium 6-hydroxy-2-naphthalene sulfonate is used as a new bifunctional activator and after high-temperature carbonization,sulfur doped porous carbon(SDPC)is synthesized.The effects of the amount of activator and temperature on the physical and chemical properties of the porous carbon are studied.The results show that when the ratio of carbon source to activator is 1∶3 and the carbonization temperature is 800℃,the sulfur content is as high as 5.82%(mass fraction),and the porous carbon has high specific surface area(1029.83 m2/g)and micropore volume(0.357 m2/g).Therefore,it can be proved that the one-step doping activation method can indeed play the dual functions of sulfur doping and activation,which provides a new idea for the preparation of heteroatom doped porous carbon.
