The high-temperature water-gas shift (HT-WGS) has received tremendous interest for the production of clean hydrogen in large scale. Iron-based oxide catalysts are widely studied for the HT-WGS reaction due to their high activity, durability, and relatively low manufacturing costs. In this review, we discussed the recent findings, especially, the role of different promoters on the HT-WGS performance of the Fe-based oxides catalyst. The review reported the recent attempts to replace the toxic Cr in the Fe/Cr-based catalysts. The article also reviews the structure-activity relations with various characterization techniques. Further, we highlighted the recent progress in understanding the catalyst structure and reaction mechanism during the reaction by in-situ and operando studies.

铁基高温水煤气变换制氢的最新进展
高温水煤气变换(HT-WGS)对于大规模生产清洁氢气引起了极大的兴趣。铁基氧化物催化剂因其高活性,耐用性和相对较低的制造成本而被广泛研究用于HT-WGS反应。在这篇综述中,我们讨论了最近的发现,尤其是不同促进剂对铁基氧化物催化剂的HT-WGS性能的作用。该评论报告了最近尝试替代铁/铬基催化剂中有毒铬的尝试。本文还回顾了各种表征技术的构效关系。此外,我们强调了通过原位和操作研究在理解反应过程中催化剂结构和反应机理方面的最新进展。
