Self-healing catalysts: CO3O4 nanorods for fischer-tropsch synthesis

摘要

A self-healing reaction process for a chemical reaction is provided by exposing a catalyst a reaction mixture that includes carbon monoxide and hydrogen gas such that hydrocarbons are produced. The catalyst includes Co₃O₄ nanorods having both Co²⁺ and Co³⁺ exposed thereon. The Co₃O₄ nanorods can have a spinel crystal structure such that the Co₃O₄ nanorods define a {110} facet having both Co²⁺ and Co³⁺ exposed thereon. During reaction conditions, water can oxidize portions of the catalyst, while the exposed Co³⁺ can reduce any oxidized portions of the catalyst such that the catalyst is self-healing during reaction conditions, especially when the reaction mixture further comprises water.
