Overview

Operando spectroscopy reveals the roles of cobalt and carbonates in the CO oxidation pathways.

Key Points

  • Cobalt-rich perovskite catalysts show enhanced activity in CO oxidation, highlighting surface dynamics.
  • Operando spectroscopy techniques uncovered two distinct reaction pathways influenced by temperature changes.
  • Kinetic analyses confirm the Mars-van Krevelen mechanisms for carbonate involvement in CO oxidation.
  • This study illustrates the influence of catalyst composition on reaction pathways and stability.
