Analysis of the surface heterogeneity of biomass based activated carbon |
| 초록 |
Biomass based activate carbons have been widely used in many applications such as gas separation, energy storage and wastewater treatment due to their unique adsorption characteristics and economic feasibility. In this work, corn-grains based ACs were prepared using two different physico-chemical methods: physical and chemical–physical activations. In order to analysis the surface heterogeneity of porous ACs, the nitrogen adsorption isotherm data measured at 77 K was used. The Frenkel–Halsey–Hill relation was used to examine the surface structural roughness of the ACs. In addition, the adsorption energy distribution functions were used to examine the energetic heterogeneity of ACs. To solve the adsorption integral equation, a general regularization method was employed. The Fowler-Guggenheim model was used as a local adsorption isotherm. In particular, the relationship between the preparation condition and the surface heterogeneity was thoroughly discussed. |
