SrxTi1–xCoO3±δ Perovskite‐like Catalysts with Enhanced Activity for Hydrogen Production

Autothermal reforming (ATR) of acetic acid (HOAc) is a promising and alternative route for hydrogen production from renewable resources, but catalyst deactivation caused by cobalt metal sintering and coking is a major concern in ATR. In this work, perovskite‐like catalysts of the formula SrxTi1–xCoO3±δ (x = 0, 0.2, 0.5, and 0.8) were prepared by evaporation‐induced self‐assembly and then evaluated in ATR for hydrogen production. The SrxTi1–xCoO3±δ catalysts exhibited high activity and stability as well as 100 % conversion of HOAc. Additionally, the Co particles with strong metal‐support interaction of SrTi(Co)O3 inhibited coking and agglomeration, and showed potential for hydrogen production by the ATR process. Autothermal reforming (ATR) of acetic acid (HOAc) from renewable resources such as bio‐oil is an alternative route for hydrogen production. Perovskite‐like ATR catalysts of the formula SrxTi1–xCoO3±δ were prepared by evaporation‐induced self‐assembly. The SrTi(Co)O3 catalyst showed high activity in the ATR of HOAc, and the strong metal‐support interaction suppressed carbon deposition and sintering.
