Abstract
The storage of hydrogen in a safe, viable manner is the greatest challenge towards the successful commercialization of hydrogen fuel cell cars. The use of metallo-organic frameworks (MOF's) seeks to make possible the storage of hydrogen gas at relatively low pressure and ambient temperature. MOF's consist of an organic compound as a ligand and metal ions which form a crystalline porous structure. However, they are not stable at high temperature. We attempt to introduce greater stability by introducing an inorganic tetrahedral moiety in the form phosphate, sulfate and other oxy-anion moieties. The metal polyhedral and the phosphate tetrahedral should form an inorganic layer, linked by the organic ligand creating a channel structure. Initial trials with terephthalic acid, the ligand and alumino-phosphate, the inorganic layer to produce what may be a more stable hybrid porous crystalline structure. The concept of hybrid strategy and initial results will be presented.
