Hello!
If you measure nitrogen sorption on CMK-3 carbon, which size do I get from the pore size distribution? Is it the distance between the carbon tubes (because it is the shortest) or do I get the size of a cylindrical pore in between?
Should I use BJH or DFT (which geometry) for the pore size analysis?
Thank you for your help!
The Nitrogen experimental isotherms simulated using Grand Canonical Monte Carlo (GCMC) method based on two kernels using slit and cylindrical pore models. From these models obtained the pore size distributions (PSD) which were compared with those obtained by Quenched Solid Density Functional Theory (QSDFT) model. The GCMC simulation showed a good agreement with experimental adsorption isotherms and some differences with the corresponding pore size distribution obtained by Density Functional Theories Methods.The nanometric carbon CMK-3 modified with Pt synthesized and applied as a reservoir for hydrogen uptake. the newly synthesized hybrid composites exhibited significantly enhanced H2 storage. The approach that we have followed includes synthesis of nanostructures with the experimental study of its adsorption capacity and storage properties. CMK-3 ordered porous carbon modified with Pt nanoclusters is a promising material for hydrogen uptake. The samples characterized by X-ray diffraction, N2 isotherms, X-ray photoelectron spectra and transmission electron microscopy. The nanoparticles of Pt (~1.7 nm) incorporated onto the nanostructured carbon CMK-3 showed higher hydrogen uptake at low and high pressures (3.3 wt% of H2 sorption at 10 bar and 77 K) than CMK-3.
