The entire data set is openly available in Zenodo. First, relevant sources of information that provide the synthetic conditions and properties of ZIF-8 particles were identified. It is important to ensure the data quality as the findings depend on these sources. Then, the information was thoroughly and systematically extracted and organized. The dataset was analyzed for verifying the accuracy and reliability of the extracted information, i.e. thus ruling out common errors arising from mistyping or scale mismatch from microscopy images. Certain relevant parameters were extracted from these articles, describing synthesis conditions employed and properties of the resulting materials. These include the source and amount of zinc, 2-methylimidazole and solvent, temperature, reaction time, and stirring conditions, as well as information on the resulting material characteristics such as particle size, morphology, and porosity. The particles' morphologies were grouped into three categories based on TEM/SEM images, namely Faceted, Poor-faceted, and Quasispherical particles.
