文摘

The Mg-decorated Fe/rGO catalysts were designed for syngas to light olefins (FTO). Mg mitigated CO2 emission by inhibiting magnetite formation. Further decoration by K drastically boosted the FTO activity. K promoted the carburization of iron and hence the activity. The synergy of Mg and K on CO dissociation may further contribute to the activity.
