Tracking Dynamics of Supported Indium Oxide Catalysts in CO 2 Hydrogenation to Methanol by In Situ TEM (Adv. Mater. 20/2025)

Tracking InO x /m‐ZrO 2 Dynamics for Green Methanol This study combines in situ transmission electron microscopy with automated, machine‐learning‐based difference imaging to classify and rank the dynamic behavior of supported indium oxide species during CO 2 hydrogenation to methanol. The results reveal that partially reduced InO x species on monoclinic zirconia undergo a cyclic mechanism involving migration, growth, reversible coalescence, and dispersion, explaining the high stability observed on this support. These insights provide a new perspective on catalyst dynamics, paving the way for more rational, data‐informed catalyst design strategies.
