Hydrogen Storage In Hypercrosslinked Polystyrene And Li-Mg-N-H Complex Hydride, Dervis Emre Demirocak Jan 2013

Hydrogen Storage In Hypercrosslinked Polystyrene And Li-Mg-N-H Complex Hydride, Dervis Emre Demirocak

USF Tampa Graduate Theses and Dissertations

In this dissertation, hydrogen storage enhancement in hypercrosslinked polystyrene, effects of single walled carbon nanotubes (SWCNTs) supported ruthenium (Ru) catalyst on the kinetics and ammonia suppression in the LiNH2-MgH2 complex hydride system and the accuracy of hydrogen storage measurements are investigated in detail.

High surface area physisorption materials are of interest for room temperature hydrogen storage enhancement by spillover. Six different commercially available hypercrosslinked polystyrenes are screened by considering the specific surface area, average pore size, pore volume, and adsorption enthalpy. MN270 is selected mainly due to its high surface area and narrow pores for investigation of the spillover enhancement …
