Kinetics of Sorption and Release of Hydrogen by Nanoporous Carbon

Materials Science Aims and scope

Abstract

We investigate the process of hydrogen sorption by nanoporous carbon at temperatures of 570–970 K by using the method of thermodesorption spectrometry. Thermodesorption spectra consist of several phases caused by chemisorption in several independent states on the surface of nanoporous carbon. Each of the states is characterized by the activation energy and pre-exponential factors of desorption rate constants. We obtain estimates for the efficient activation energy and heat of sorption.
