以酚醛树脂为原料，采用水热法制备了球形活性炭，并采用不同的掺杂策略将含氮官能团引入到活性炭中。通过N2物理吸附和扫描电镜（SEM）表征了样品的织构性质，并通过热重法和高压体积法评价了样品在常压和高压下的CO2吸附行为。通过将不同样品的CO2吸收量与其织构性质和表面亲和力相关联，建立了结构-性能关系。结果发现，AC珠是一个合适的选择，现实的CO2捕获，特别是在燃烧前的捕获，其中CO2分压相对较高。
Activated carbon (AC) beads with desirable spherical forms were prepared from phenolic resins using a novel hydrothermal process coupled with a range of post-preparation treatments, and different strategies were employed to dope N-containing functionalities into the AC beads. Texture properties of the samples were characterized by N2physisorption and scanning electron microscope (SEM), and the CO2adsorption behavior was evaluated at both ambient and elevated pressures by using either thermal gravimetric or high pressure volumetric analysis method. By relating the CO2uptakes of different samples with their texture properties and surface affinity, a structure–performance relationship was established. It was found that the AC beads are a suitable option for realistic CO2capture, especially in pre-combustion capture where CO2partial pressure is relatively higher.
