A collaborative effort between scientists in the United States and Spain has succeeded in predicting quantitative hydrogen uptake at pressures up to 80 atmospheres on microporous carbons from laboratory data acquired at cryogenic conditions below 1 atm pressure. The methods and results are described in a paper entitled "DFT-Based Prediction of High-Pressure H2 Adsorption on Porous Carbons at Ambient Temperatures from Low-Pressure Adsorption Data Measured at 77 K" published in the Journal of Physical Chemistry B Letters, available on the web 2/18/2006 (http://pubs.acs.org/cgi-bin/abstract.cgi/jpcbfk/asap/abs/jp057340x.html ) authored by Dr Jacek Jagiello (USA), Alejandro Anson and M. Teresa Martinez (both Spain). Not only are high pressure amounts correctly predicted, but the cryogenic data also generates a pore size distribution which should be a useful tool for optimizing carbon pore structures and designing adsorption systems for hydrogen storage applications.
Dr Jacek Jagiello, Quantachrome Instruments, USA Dr Jagiello is well known in the field of microporous carbon characterization, having authored and co-authored more than 80 scientific publications including two book chapters, given more than 20 presentations at international conferences and holds four U.S. patents. He gained his PhD in 1984 under Prof. W. Rudzinski on the thermodynamics of physical adsorption on heterogeneous surfaces.
Alejandro Anson and M. Teresa Martinez, Instituto de Carboquimica, CSIC, Spain The CSIC is the largest public research body in Spain. The Institute of Carbon Chemistry is one of its Institutes and is located in Zaragoza. The Institute has equipment and experimental techniques to synthesise and characterize carbons and carbonaceous products for enviromental, catalysis and advanced engineering applications. Much of the work focuses on new and unconventional methods and materials.
