Hydrogen economy in the forthcoming years demands a need to find viable methods for on-board storage of hydrogen for transportation purposes. Sub-nanostructured metal grids are developed for hydrogen absorption in storage applications. Metal phase is grown into a zeolite mold, which is uniformly grown on the cathode by in-situ hydrothermal synthesis of zeolites. The various parameters involved in modeling in-situ hydrothermal synthesis of zeolite are Al/Si ratio, synthesis reaction chemistry, time-temperature combination for the synthesis, and the substrate used for zeolite deposition. Various zeolites synthesized for developing a zeolite layer are faujasite, mesoporous silica and silicalite. Micro-scale roughening of the metal surface serves as nucleation sites during zeolite synthesis and thus provides better adhesion between the metal and zeolite film. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
