摘　　要：硫掺杂多孔炭因具有优异的理化性质在很多方面都显示了巨大的潜力。本文以来源广泛、经济实惠且对环境友好的葡萄糖为原料,使用6-羟基-2-萘磺酸钾作为一种新型双功能活化剂经过高温炭化后直接合成硫掺杂的多孔炭(SDPC),同时深入研究活化剂添加量和温度对该多孔炭物理化学性质的影响。结果表明,当碳源与活化剂质量比例为1∶3,炭化温度为800℃时,硫含量高达5.82%(质量分数),且该多孔炭具有高比表面积(1029.83 m^(2)/g)与微孔体积(0.357 m^(2)/g)。该结果说明一步掺杂活化法可以起到掺硫与活化的双重功能,为制备杂原子掺杂多孔炭提供了一种新思路。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 m^(2)/g)and micropore volume(0.357 m^(2)/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.
