Trends in Green Chemistry Research between 2012 and 2022: Current Trends and Research Agenda

Abstract

Traditional chemistry is undergoing a transition process towards a sustained paradigm shift under the principles of green chemistry. Green chemistry is emerging as a pillar of modern chemistry focused on sustainability. In this context, the aim of this study was to analyse green chemistry research and its contributions using quantity, quality, and structural indicators. For this purpose, data were retrieved from Scopus and Web of Science through a structured search equation for the study period, i.e., 2012 to 2022. These data were compiled and processed in Microsoft Excel version 2307, totalling 2450 records. VOSviewer software, version 1.6.18, was used to map the keyword network and for overlay and density visualisations. The results showed that green chemistry is constantly increasing in different fields of knowledge, with new studies in green solvents, eutectic solvents, and education for sustainable development. The number of publications peaked in 2019, slightly decreasing in subsequent years due to the novel coronavirus disease 2019 (COVID-19) pandemic. As visualised through VOSviewer, the keyword “sustainability” is connected to all clusters, and green synthesis, catalysis, sustainability, curriculum, and higher degrees are leading trends in green chemistry research. The study could benefit researchers and professionals interested in green chemistry and sustainability.
