| Abstract: |
| The effective active site of biomass carbon is restricted by its pore type and pore size. The activity of biomass carbon is effeted by its pore type and pore size. With the research of biomass actual adsorption desorption isotherm is irregular. It is difficult to match the IUPAC adsorption desorption isotherm.Therefore, this article proposes a new method for pore classification based on carbon materials, the analysis of pore is more and more accurate which scientific researchers'' needs. The pores of biomass carbon materials are classified by matching the actual adsorption desorption isotherm and the IUPAC adsorption desorption isotherm. However, the porosity and specific surface area occupancy. The biomass carbon materials were prepared and characterized by N2- adsorption. The pores of the biomass carbon materials are analysied by the BET equation, T-plot method, DFT method, and BJH method. The result show that the biomass carbon can accurately defined microporous materials, mesoporous materials, and micro mesoporous materials by porosity and specific surface area occupancy. The new method for pore classification of porosity and specific surface area is demonstrated by standard samples.Which the results are consistent. So the new method for pore classification based on porosity and specific surface area occupancy is accurate, reliable, and highly practical. |
