As an expert-curated resource, the CAS content is utilized here for the quantitative analysis of publications against variables including time, country/region, research area, and substance details. Homogeneous catalysts query (see SI for more details) was used to retrieve documents that are specific to reports discussing using sustainable catalysts for homogeneous catalysis and/or the studies for the replacement of noble-metal catalysts. A total of 7865 documents were used for the analysis described below.
