以三聚氯氰和噻吩为反应单体,通过简单的傅克烷基化反应制备含N 、 S多孔有机聚合物(PCT),进而以PCT为碳前驱体,采用氢氧化钾活化法在不同温度下碳化得到N.S共掺杂微孔碳材料(CPCT-X),研究碳化温度对材料比表面积和孔径的影响规律,并考察具有不同孔结构和杂原子含量微孔碳材料的CO 2 捕集性能和电化学性能。结果表明:CPCT-X具有较大的比表面积(1629 m 2 · g -1 )和高微孔孔隙率(96.7%),碳化温度为600 ℃ 时,具有最好的CO 2 捕集性能(5.5 mmol/g,273K,0.1MPa);同时,CPCT-X具有很好的超电性能,当碳化温度为700 ℃ 时,比电容可达210F/g(电流密度为0.5A/g)。
- Abstract:

N,S-Co doped microporous carbons (CPCT-X) were prepared by potassium hydroxide activationmethod at different carbonization temperatures using porous organic polymer (PCT) synthesized by a simpleFriedel-Crafts alkylation reaction between melamine and thiophene as carbon precursors. The effect of carboni-zation temperature on the BET and pore sizes was investigated, and the CO 2 , capture and electrochemistry prop-erties of CPCT-X with different pore structures and N,S contents were also conducted. The results suggestedthat CPCT-X had a large specific surface area (1629 m 2 ·g -1 ) and high micropore porosity (96.7%) , andshowed a good CO 2 , capture performance at the carbonization temperature of 600 ℃ (5.5 mmol/g, 273 K,0.1 MPa). Meanwhile, the specific capacity could reach 210 F/g at a current density of 0.5 A/g when thecarbonization temperature was 700 ℃ .
