To gain a more comprehensive understanding of the literature, we integrated the aforesaid analyses to understand how those electrolytes are combined with the selected elements. Since all the information required is seldom available in a single sentence, our strategy involved combining relevant data based on file names. In other words, we considered a pair element-electrolyte only if both element and electrolyte were extracted from the same file. Furthermore, we also analyzed the co-occurrence of elements and electrolytes with CO 2 RR and HER products. We investigated how frequently they are positively mentioned with the products CH 4 , CH 3 OH, C 2 H 4 , C 2 H 5 OH, C 3 H 7 OH, HCOOH, HCOO -, H 3 CCOOH, H 3 CCOO -, C 3 H 8 , C 4 H 10 , C 4 H 9 OH, CO and H 2 . By "positive" we mean that sentences that do not contain negative terms such as "no", "don't" or "didn't". We intentionally disregarded sentences such as "we observed no methane production during the reaction" to avoid false positives in pairs element-product or electrolyte-product. Although it is not guaranteed that a particular element can favor a specific product simply by analyzing the frequency they co-occur, this result can provide an overview of the relationship between different elements or electrolytes and their impact on the selectivity of the reaction. We also notice here that this is the only step in our pipeline in which we used a dictionary lookup, to match product formulae.
