Carbon-based adsorbents with a high adsorption capacity and low price have been widely used in the removal of volatile organic compounds (VOCs), but the poor gas selectivity and reusability limit their industrial applications. In this work, disc-like nitrogen-rich porous carbon materials (HAT-Xs) were synthesized to remove typical VOCs via adsorption. By controlling the synthesis temperature from 450 to 1000 °C, the C/N ratio of the HAT-Xs increased from 1.85 to 12.56. The HAT-650 synthesized at 650 °C with the high specific surface area of 305 m² g⁻¹ exhibits the highest adsorption capacity of 141 mg g⁻¹ for ethyl acetate (which is 3.2 times for that of activated carbon), and 39.4 mg g⁻¹ for n-hexane, 48.6 mg g⁻¹ for toluene. Kinetic studies indicated that the adsorption is physical adsorption and that the interior surface diffusion is the main rate-determining step during the adsorption progress, the interior surface diffusion rate of ethyl acetate on HAT-650 is 1.455 mg g⁻¹ min^−0.5. At the same time, the desorption and reuse tests show that HAT-650 has excellent reusability with low desorption and regeneration temperature of 120 °C, and high desorption efficiency of 95.2% and that it could be a promising ethyl acetate adsorbent for industrial applications.

碳基吸附剂具有吸附能力高、价格低廉的特点，已广泛应用于挥发性有机化合物（VOCs）的去除，但气体选择性和重复使用性差，限制了其工业应用。在这项工作中，合成了盘状富氮多孔碳材料 (HAT-Xs)，以通过吸附去除典型的 VOC。通过将合成温度控制在 450 到 1000°C，HAT-Xs 的 C/N 比从 1.85 增加到 12.56。在 650 ℃合成的 HAT-650 具有 305 m ² g ^-1的高比表面积，对乙酸乙酯的吸附容量最高，为 141 mg g ^-1 （是活性炭的 3.2 倍），39.4正己烷的 mg g -1，48.6 ^mg g ^-1对于甲苯。动力学研究表明吸附是物理吸附，内表面扩散是吸附过程中主要的速率决定步骤，乙酸乙酯在HAT-650上的内表面扩散速率为1.455 mg g ^-1 min ^-0.5。同时，解吸再利用试验表明，HAT-650具有优异的重复利用性，解吸再生温度低至120℃，解吸效率高达95.2%，是一种很有前景的工业化乙酸乙酯吸附剂。
