Two decades of research on green inhibition of steel corrosion: A bibliometric review

This work proposes an in-depth bibliometric analysis of the scientific publications on medicinal plant extracts as inhibitors of steel corrosion. The objective is to identify research trends, the most influential authors, the most active countries, as well as the evolution of citations over time. Based on the data extracted from the “Scopus” database, the study uses “R Studio” for data analysis and “VOS viewer” for network visualizations. The results reveal a significant growth in the number of publications and citations from 2011 onwards, with a peak in activity between 2017 and 2022. The main contributors to this research are India, China, Morocco, and Iran, whose researchers and institutions have played a crucial role in advancing research in this field. This study highlights the major lines of research and offers an overview of the prospects in this rapidly expanding field.
