Our comprehensive pipeline for extracting various types of information from scientific publications focused on the reduction of CO 2 /CO into high-value products. The pipeline encompasses the extraction of categorical and numerical data, specifically the composition of catalysts, the utilization of electrolytes in CO 2 ER, and the faradaic efficiency (FE) towards different products of CO 2 RR. Furthermore, we combined these extracted data to gain valuable insights from the literature and conducted an annual analysis to identify trends in this research field. Our findings suggest that bismuth (Bi) exhibits promise as a material for hydrogenating CO 2 into formate (HCOO -). Bi is frequently mentioned alongside formate and demonstrates a significantly high median FE while displaying a distinct pattern of least co-occurrence with hydrogen (H 2 ).
