Abstract
Modern society relies on oil and hydrocarbon to satisfy its energy requirements. However the usage of oil is depleting the world resources and increase the emission of greenhouse gases, leading to grave consequences for the whole planet. In this optics the research for new cleaner and renewable energy sources is necessary more than needed, between this hydrogen has created a lot of interest as both fuel and energy carriers.
Hydrogen has an energy density three times higher than petroleum, 120 kJ g-1, that can be released with high efficiency using fuel cell systems combined with electrical engines. Moreover fuel cells are really clean energy systems that produce only water as by-product, in this way the level of pollutant and greenhouse gases in the atmosphere.
Main drawback for hydrogen application is the need to find an efficient and safe method of transportation. From this point of view chemical liquid storage system like hydrazine and formic acid are really promising platform for large scale application of fuel cell system. We used iridium-based catalysts to catalyse the decomposition of hydrous hydrazine into molecular hydrogen and nitrogen . The catalyst have been prepared using differents preparation methods like deposition-precipitation and sol-immobilisation, and bimetallic systems using other metals such as Fe and Ni.
