A corpus of CO2 Electrocatalytic Reduction Process extracted from the scientific literature

In this data descriptor, we present an open-source corpus, a collection of 6,086 records extracted from a database of 835 publications, labeled manually by expert catalytic curators, following annotation guidelines specifically defined for this task. In this corpus, we extracted nine types of knowledge, including material, regulation method, product, faradaic efficiency, cell setup, electrolyte, synthesis method, current density, and voltage.
