| 摘 要： | 以木质素为原料，采用管式炉反应器通过一步热解-半活化法获得木质素基多孔炭材料（LPC）。采用氮吸附（BET）、扫描电镜（SEM）和傅里叶变换红外光谱（FTIR）对多孔炭材料的物化性质进行分析。在900℃的恒定炭化温度下，CO2体积分数为6%、水蒸气体积分数约为20%时，LPC-C6S20表面具有良好的纳米结构，并且总孔容和比表面积分别达到0.77cm3/g和1497.51m2/g，活化气氛促进了多孔炭材料颗粒趋于均匀和微孔、中孔的形成。LPC样品含有—OH、C—H、C＝C、C—O、C＝O、CO—C、C—N、C＝N等丰富的表面官能团。随着活化剂浓度的变化，这些官能团保持相对稳定。因此，通过该方法获得的样品具有良好的纳米结构，具有较大的孔容、比表面积和表面官能团。 |

| Abstract: | The lignin-based porous carbon material (LPC) was obtained by using lignin as raw material and tube furnace reactor through a one-step pyrolysis-activation method. Nitrogen adsorption (BET), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to analyze the physical and chemical properties of porous carbon material. At a constant carbonization temperature of 900℃ with CO2 concentration of 6% and water vapor concentration of about 20%, the surface of LPC-C6S20 had a good nanostructure, and the total pore volume and specific surface area reached 0.77cm3/g and 1497.51m2/g, respectively. The activation atmosphere promoted the uniformity of porous carbon material particles and the formation of micropores and mesopores. The LPC sample contained abundant surface functional groups such as —OH, C—H, C＝C, C—O, C＝O, CO—C, C—N and C＝N, etc. As the concentration of the activator changed, these functional groups remained relatively stable. Therefore, the sample obtained by this method had a good nanostructure with a larger pore volume, specific surface area and functional groups. |
