Aiming at the problems of high chemical inertness of high-rank anthracite, high energy consumption and high pollution of traditional activation process, a two-step process of potassium ferrate activation-thiourea gas phase doping was used to prepare high-performance nitrogen and sulfur co-doped porous carbon. The effects of activation temperature, mass ratio of potassium ferrate to coal and activation time on the preparation of porous carbon CDC were investigated by Box-Behnken method. Then, nitrogen and sulfur were doped into thiourea gas phase to obtain NS-3-850. The microstructure and surface chemical properties were characterized by SEM-EDS, XRD, Raman and XPS. The electrochemical properties were tested by CV and GCD methods. The results show that the method effectively constructs a hierarchical pore structure dominated by micropores and coordinated by mesopores, and successfully introduces nitrogen-and sulfur-containing functional groups into the carbon skeleton. The obtained nitrogen and sulfur co-doped porous carbon has a high specific surface area (1 393 m2/g) and an optimized mesoporous ratio (33.69%). The pore structure is suitable for ion diffusion and the surface functional groups are improved. NS-3-850 exhibits good energy storage performance in 6 mol/L KOH electrolyte, and the specific capacitance is 220 F/g at current density of 0.5 A/g. The preparation process provides a feasible technical path for the directional conversion and functionalization of inert coal by wet chemical means.

针对高阶无烟煤化学惰性强、传统活化工艺能耗高、污染大等问题,研究了采用“高铁酸钾活化—硫脲气相掺杂”分步工艺制备高性能氮硫共掺杂多孔炭。通过Box-Behnken方法考察了活化温度、高铁酸钾与煤质量比、活化时间对制备多孔炭CDC的影响,继而硫脲气相掺杂氮、硫元素得到NS-3-850氮硫共掺杂多孔炭样品,并通过SEM-EDS、XRD、Raman、XPS等手段表征了其微观结构与表面化学性质,借助CV、GCD方法测试了其电化学性能。结果表明:该方法有效构建了以微孔为主、介孔协同的多级孔结构,并成功将含氮、硫官能团引入碳骨架;所得氮硫共掺杂多孔炭具有高比表面积(1 393 m2/g)和优化的介孔比例(33.69%),其孔结构适合离子扩散,且表面官能团得到改善;NS-3-850在6 mol/L KOH电解液中表现出良好的储能性能,在0.5 A/g电流密度下的比电容为220 F/g。该制备工艺为通过湿法化学手段实现惰性煤种的定向转化与功能化提供一种可行的技术路径。

针对高阶无烟煤化学惰性强、传统活化工艺能耗高、污染大等问题,研究了采用“高铁酸钾活化—硫脲气相掺杂”分步工艺制备高性能氮硫共掺杂多孔炭。通过Box-Behnken方法考察了活化温度、高铁酸钾与煤质量比、活化时间对制备多孔炭CDC的影响,继而硫脲气相掺杂氮、硫元素得到NS-3-850氮硫共掺杂多孔炭样品,并通过SEM-EDS、XRD、Raman、XPS等手段表征了其微观结构与表面化学性质,借助CV、GCD方法测试了其电化学性能。结果表明:该方法有效构建了以微孔为主、介孔协同的多级孔结构,并成功将含氮、硫官能团引入碳骨架;所得氮硫共掺杂多孔炭具有高比表面积(1 393 m2/g)和优化的介孔比例(33.69%),其孔结构适合离子扩散,且表面官能团得到改善;NS-3-850在6 mol/L KOH电解液中表现出良好的储能性能,在0.5 A/g电流密度下的比电容为220 F/g。该制备工艺为通过湿法化学手段实现惰性煤种的定向转化与功能化提供一种可行的技术路径。

Aiming at the problems of high chemical inertness of high-rank anthracite, high energy consumption and high pollution of traditional activation process, a two-step process of potassium ferrate activation-thiourea gas phase doping was used to prepare high-performance nitrogen and sulfur co-doped porous carbon. The effects of activation temperature, mass ratio of potassium ferrate to coal and activation time on the preparation of porous carbon CDC were investigated by Box-Behnken method. Then, nitrogen and sulfur were doped into thiourea gas phase to obtain NS-3-850. The microstructure and surface chemical properties were characterized by SEM-EDS, XRD, Raman and XPS. The electrochemical properties were tested by CV and GCD methods. The results show that the method effectively constructs a hierarchical pore structure dominated by micropores and coordinated by mesopores, and successfully introduces nitrogen-and sulfur-containing functional groups into the carbon skeleton. The obtained nitrogen and sulfur co-doped porous carbon has a high specific surface area (1 393 m2/g) and an optimized mesoporous ratio (33.69%). The pore structure is suitable for ion diffusion and the surface functional groups are improved. NS-3-850 exhibits good energy storage performance in 6 mol/L KOH electrolyte, and the specific capacitance is 220 F/g at current density of 0.5 A/g. The preparation process provides a feasible technical path for the directional conversion and functionalization of inert coal by wet chemical means.
