摘要：以间苯二酚-甲醛基炭气凝胶为原料,磷酸氢二铵((NH_(4))_(2)HPO_(4))为活化剂和N源、P源双原子掺杂剂,通过简单的固相物理研磨混合,经热解制备了N/P共掺杂活化的炭气凝胶(NP-CAs),一步法完成了炭气凝胶的活化和双原子掺杂。研究结果表明,当热解温度为900℃,(NH_(4))_(2)HPO_(4)与CAs的掺杂比(质量比)为1∶2时,所制备的改性炭气凝胶的比表面积达到1196.75 m^(2)/g,总孔体积为1.60 cm^(3)/g;成功实现了N/P双原子的掺杂和均匀分布;N和P的质量分数分别达到了0.54%和0.13%;亲水性得到大幅度提升;在三电极体系下,当电流密度为1.0 A/g时,其比电容可达150 F/g,并保持了相当高的循环寿命。
In order to explore a multi-functional activator for carbon aerogel to improve its electrochemical performance,we used resorcinol-formaldehyde based carbon aerogel as the raw material and(NH4)2HPO_(4)as the activator,N source and P source.Then,we prepared N/P co-doped activated carbon aerogels(NP-CAs)via solid-phase physical grinding and mixing.The activation and diatomic doping of carbon aerogels were completed via one step method.The results showed that when the pyrolysis temperature was 900℃and the mass ratio of(NH4)2HPO_(4)and CAs was 1∶2,the sample had a specific surface area of 1196.75 m^(2)/g and a total pore volume of 1.60 cm^(3)/g.The doping and uniform distribution of N/P dopants were successfully achieved.The mass fractions of N and P reached 0.54%and 0.13%,respectively.The hydrophilicity was greatly improved.In the three-electrode system,it exhibited a high specific capacitance of 150 F/g at a current density of 1.0 A/g.It also remained a quite high cycle life.
