A scientific article titled, “Effects of CO² activation of carbon aerogels leading to ultrahigh micromeso porosity
” co-authored by Dr. Jacek Jagiello has recently been published in ScienceDirect. The effects of CO²
activation on the porosity of ultrahigh pore volume carbon aerogels is analyzed. The new 2D-NLDFT-HS model for carbons data obtained has been compared to the results of conventional methods (BJH, t-plot, DR); all the models were applied to the desorption branch of the isotherms. Materials showing increasing volume of micropores and alteration of mesopore structure occurred physical activation of the carbon aerogel at different burn-off degrees. The later effect manifested itself by a characteristic inflection in the desorption branch of the nitrogen isotherm at high relative pressures.
Highlights of the article include:
- Assessment of textural properties of ultrahigh pore volume carbon aerogels.
- Comparison of 2D-NLDFT-HS model with conventional methods (BJH, t-plot).
- Activation created curvatures in the nitrogen adsorption/desorption isotherms.
- CO² activation of the carbon aerogel modified both micro and mesopore structure.
- The non-uniform activation created bimodal/multimodal pore size distributions.
