This dataset is a catalyst simulation dataset jointly launched by FAIR and Carnegie Mellon University in 2022, namely Open Catalyst 2022 (OC22) Dataset. This dataset is an expansion and supplement of the OC20 dataset, including more complex catalyst structures and new reaction types, providing richer data for training and testing AI models.The Open Catalyst 2022 (OC22) Dataset and Challenges for Oxide Electrocatalysts".
