Gas storage in porous materials - searching for exceptional performance over the complete adsorption-storage-delivery cycle

Russell E. Morris, St Andrews, UK

Gas delivery technologies using solid storage materials are of increasing importance in many areas of science, with emerging applications that include the storage of hydrogen and methane as energy carriers and the delivery of nitric oxide (NO) for medical therapies. A perfect gas storage solid will have high adsorption capacity and kinetics (at workable temperatures), and the gas should interact strongly enough with the material so that it is not lost from the solid on storage but not so strongly that it cannot be released from the material for use at the required time. The release should also occur at the appropriate rate for the desired application. Most suggested gas storage materials fall down on one or more of these criteria. In this presentation I will discuss our search for the perfect nitric oxide storing materials, explaining the rationale behind our choice of materials and then describe the applicability of these materials including the initial trials on human skin.
