Biomass-Derived Adsorbents for CO2 Capture: Trends and Bibliometric Insights

Abstract

Increased fossil fuel usage and deforestation disrupt CO2 balance, exacerbating climate change. A multifaceted approach should be implemented to mitigate the effects of climate change, including sustainable resource management and increased utilization of alternative energy sources. In this process, CO2 capture has emerged as a promising method, with adsorbents playing a critical role. Currently, biomass-based adsorbents, especially those derived from organic bio-waste, are materials of significant interest in the field of CO2 capture due to their unique properties and environmental advantages. This study presents a comprehensive bibliometric analysis of research conducted on adsorbents with high CO2 capture capacities derived from biomass or organic waste sources, aiming to identify trends in this field and evaluate methodologies. Since 1995, over 1500 scientific publications were collected based on selected keywords and manually screened for relevance. In the bibliometric analysis, key data such as authors, affiliated institutions, countries, and research areas were presented, and datasets were compiled for performance analysis and scientific mapping. Web of Science (WoS), one of the most commonly used multidisciplinary databases today, was utilized for data collection and analysis, and VOSviewer software was employed for mapping. In conclusion, this study maps the landscape of the relevant field by identifying significant contributors, relevant keywords, field categories, and research approaches, serving as a strategic tool for researchers to recognize progress, trends, and gaps to guide future studies.
