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 Sr_xTi_1–xCoO_3±_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 Sr_xTi_1–xCoO_3±_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.

SrxTi1–xCoO3±δ 类钙钛矿催化剂，具有增强的制氢活性

乙酸 (HOAc) 的自热重整 (ATR) 是从可再生资源制氢的一种有前景的替代途径，但由钴金属烧结和焦化引起的催化剂失活是 ATR 中的一个主要问题。在这项工作中，通过蒸发诱导自组装制备了分子式为 Sr _x Ti _1–x CoO _3±_δ ( x = 0, 0.2, 0.5 和 0.8)的类钙钛矿催化剂，然后在 ATR 中评估其制氢能力. Sr _x Ti _1-x CoO _3±_δ催化剂表现出高活性和稳定性以及 100% 的 HOAc 转化率。此外，具有强金属-载体相互作用的 SrTi(Co)O ₃的 Co 颗粒抑制焦化和团聚，并显示出 ATR 工艺制氢的潜力。
