The latter could explain the challenge of finding materials with suitable band alignment for OER. As an alternative, other oxidation half-reactions have already been proposed to couple with HER. We can also summarize these results by plotting the UMAP projection of the 768dimensional vector that has not been fine-tuned to any of the descriptors. In the sequence in It is interesting to compare these numbers for the QMOF and CDP-MOFs. We note that the CDP-MOFs database has indeed a significantly higher percentage of structures that meet two or more criteria than the QMOF database, based on both MOFTransformer (Figure )
