▎ 摘　　要

Organics including terephthalic acid and glucose are added to selectively adsorb on iron oxide or graphene oxide, which can further modify the structure properties and metal-support interaction of iron oxide/reduced graphene oxide catalysts. The proper metal-support interaction is favorable for the reduction and carburization of iron oxide to form more active sites for CO hydrogenation. Thus, higher CO conversion and heavier hydrocarbons are achieved over organics modified catalysts. This simple, eco-friendly and economic viable method opens a new avenue from molecular level for the design of highly active supported catalysts.
