Abstract
Hydrogen adsorption on carbon based adsorbents was studied via synthesizing modified version of carbons by incorporating Boron and other heteroatoms. Presence of heteroatoms changed force field energy in the pores and the interaction energy distribution between H 2 molecules and the adsorbent surface. At room temperature carbon adsorbents are believed to be able to adsorb H 2 with 9 KJ/mol. Theoretically, incorporation of boron can increased with value to 12 KJ/mol. This changes is attributed to the electon deficiency of boron. XRD, XPS and TEM techniques were utilized to characterize the synthesized materials. XPS confirmed incorporation of ∼ 17 (atomic)% boron in carbon structure. A sample with 700 m 2/g surface area and ∼12 KJ/mol was synthesized. Besides, presence of turbostratic regions was verified by XRD patterns and TEM images.
