摘要:
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 ,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 ,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 activation method at different carbonization temperatures using porous organic polymer (PCT) synthesized by a simple Friedel-Crafts alkylation reaction between melamine and thiophene as carbon precursors. The effect of carbonization temperature on the BET and pore sizes was investigated, and the CO2 capture and electrochemistry properties of CPCT-X with different pore structures and N, S contents were also conducted. The results suggested that CPCT-X had a large specific surface area (1 629 m2·g-1) and high micropore porosity (96.7%), and showed a good CO2 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 the carbonization temperature was 700 ℃.
