The authors say "The pore size distribution calculated by using the density functional theory (DFT) method", but no data could support this statement.
以下是本人在论文中的描述
The porous property of the sample was examined by nitrogen sorption analysis at 77 K. The adsorption isotherm shows a sharp nitrogen gas uptake at low relative pressure demonstrating an extensive micropore structure and a slight hysteresis loop suggesting the presence of mesopores in the material. The pore size distribution calculated by using the density functional theory (DFT) method also confirmed the existence of both micropores and mesopores.
论文中测试计算方法描述
The samples were degassed at 100 ℃ for 8 h before the measurements. Surface areas were calculated from the adsorption data by using Brunauer-Emmett-Teller (BET) methods. The pore size distribution curves were obtained from the adsorption branches by using the density functional theory (DFT) method.
