Quantifying uncertainty in catalyst activity and deactivation during CO 2 hydrogenation via round-robin testing for data-driven modelling

Nature Catalysis, Published online: 31 July 2026; doi:10.1038/s41929-026-01559-y This Analysis presents a round-robin study of Rh/TiO2 catalysts for CO2 hydrogenation across four laboratories, quantifying both intralaboratory and interlaboratory variability and discussing the implications of this uncertainty for machine learning predictions.
