Kinetics of Hydrogen Uptake and Release from Heteroaromatic Compounds for Hydrogen Storage

摘要: The kinetics of hydrogen uptake by N-ethylcarbazole and carbazole, the H2 release from their hydrogenated products, is reported. hydrogenation at 130−150 °C on Ru was well described a network first-order stepwise reactions. significantly faster than in both cases, >95% selectivity to completely dodecahydro-N-ethylcarbazole dodecahydrocarbazole, achieved. dehydrogenation 101 kPa 150−170 °C, proceeded 100% conversion reactant over Pd catalyst within 1 h. However, only 69% stored recovered due low N-ethylcarbazole. In case dodecahydrocarbazole 170 same catalyst, 28% recovery obtained strong adsorption product carbazole surface that also resulted slower r...
