Dataset: Quantifying Uncertainty in Catalyst Activity and Deactivation during CO2 Hydrogenation via Round-Robin Testing for Data-Driven Modeling

Source data for the following publication: Quantifying uncertainty in catalyst activity and deactivation during CO2 hydrogenation via round-robin testing for data-driven modelling, Nature Catalysis, 2026. Dataset 1 – Full Round-Robin Dataset (Fig2-5.zip): This dataset contains all measurements from the four laboratories, including catalyst reactivity and associated experimental metadata. It supports the results presented in Figs. 2–5 of the manuscript. Dataset 2 – Low-Conversion Dataset (Fig6.zip): This dataset contains measurements under low-conversion conditions, including catalyst reactivity and associated experimental metadata. It supports the results presented in Fig. 6 of the manuscript.
