Structural aspects of activation and deactivation of cobalt catalysts in hydrogenation of carbon dioxide

摘要: Publisher Summary The hydrogenation of carbon dioxide to methane and other hydrocarbons is an interesting catalytic alternative the Ftscher–Tropsch reaction. One metals known be active for this process cobalt. To get a better understanding process, it great interest elucidate microscopic processes taking place in various steps. Included are structural chemical changes catalyst surface, which most likely influence overall performance or activation deactivation catalyst. Concerning on cobalt, pioneering work by Amariglio et al . revealed correlations between activation/deactivation behavior oxidizing pretreatments catalysts. Intensive studies were also performed CO supported Co catalysts providing comprehensive background 2 hydrogenation. However, resent results showed that compact material reveals different aspects. Thus, based earlier work, chapter focuses thorough investigation respective properties system materials. achieve extensive information, experimental includes broad variety methods both groups Erlangen Krakow.
