美國麥克儀器公司研究人員發(fā)表2D-NLDFT研究進(jìn)展：結(jié)合N₂等溫吸附線和CO₂等溫吸附線表征微孔炭材料的孔結(jié)構(gòu)。
美國麥克儀器公司的研究人員Jacek Jagiello博士，在CARBON上發(fā)表一篇題為Dual gas analysis of microporous carbons using 2D-NLDFT heterogeneous surface model and combined adsorption data of N₂ and CO₂（http://www.sciencedirect。。ｃｏｍ/science/article/pii/S0008622315004005）的研究文章，該文章使用我公司推出的2D-NLDFT的雙等溫線模型，對微孔炭材料的孔徑分布進(jìn)行了表征，得到了非常理想的結(jié)果，將炭材料的表征研究進(jìn)一步向前推進(jìn)。
該dual 2D-NLDFT已經(jīng)嵌入到麥克氣體吸附儀的軟件MiroActive中。

該文章摘要如下：

Knowledge of the pore structure of carbon materials including micropores is crucial for applications such as double layer supercapacitors, gas separation, and other applications requiring high specific surface area materials. High surface area is always associated with fine micropores. The pore size distribution (PSD) of microporous carbons is usually evaluated from nitrogen adsorption isotherms measured at 77 K in the relative pressure range from 10?7 to 1. Due to the very slow gas diffusion into fine pores at cryogenic temperatures and low pressures, the adsorption measurements may be extremely time consuming and sometimes inaccurate when the adsorption equilibrium is difficult to achieve during the measurement. In this work, we discuss an approach in which the carbon PSD is calculated from the combined N2 and CO2 data measured in the pressure range from 1 to 760 Torr. Under such conditions, the diffusion into micropores is usually fast and equilibration times are short for both measurements. In the PSD calculations we use 2D-NLDFT models for carbons with heterogeneous surfaces (J. Jagiello and J.P. Olivier, Adsorption19, 2013, 777–783). We show that both isotherms can be fitted simultaneously with their corresponding models and as a result the unified PSD can be obtained
