Transition from chemisorption to physisorption of H2 on Ti functionalized [2,2,2]paracyclophane: A computational search for hydrogen storage

Hydrogen Storage by Physisorption on Porous Materials

Chemisorption sites of CO on small gold clusters and transitions from chemisorption to physisorption.

Gold clusters adsorbed with CO, Au(m)(CO)(n) (-) (m=2-5; n=0-7), were studied by photoelectron spectroscopy (PES). The first few CO adsorptions were observed to induce significant redshifts to the PES spectra relative to pure gold clusters. For each Au cluster, a critical CO number (n(c)) was observed, beyond which the PES spectra of Au(m)(CO)(n) (-) change very little with increasing n. n(c) w...

IV.D.2 Hydrogen Storage Materials with Binding Intermediate between Physisorption and Chemisorption

This project aims to develop new porous hydrogen storage materials which utilize molecular chemisorption of hydrogen rather than mere physisorption, and ultimately do this in low weight hybrid materials. Stronger binding of hydrogen should result in greater capacity and lower operating pressures at room temperature. These studies should lead to the design and synthesis of hydrogen storage mater...
