Adsorption of Nickel as Waste Contaminant using Nano-Sustainable-Based Particle Material: From a Bibliometric Perspective

Abstract

Adsorption is a crucial area of study, particularly in material technology and environmental management. A literature evaluation, bibliometric analysis, and visualization of scientific publications about the subject of adsorption from 2014-2024 are the objectives of this work. By using publication data from the Scopus database, which has gathered and retrieved 1,522 publication papers, bibliometric analysis was carried out. This study examined several factors, such as (i) the year-over-year increase in research publications; (ii) the most cited articles; (iii) the most influential countries, journals, and institutions; (iv) the features of research documents; (v) productive research fields; and (vi) network and overlay visualization. The analysis's findings indicate that rising environmental consciousness around the world led to a notable rise in publications between 2021 and 2022. The most significant research uses eco-friendly nanoparticles for sustainable adsorption. While Chinese organizations like the Chinese Academy of Sciences and the Ministry of Education of the People's Republic of China dominate research contributions, motivated by local industry demands, the Journal of Colloid and Interface Science is the major journal in this field. The nations that have made the biggest contributions to research are China, India, and the United States. Chemistry, environmental science, chemical engineering, and materials science comprise the majority of the publications (83.3%). Three primary groupings are depicted in the topic visualization: particles, sustainability, and removal. The latest research trends include studies on the removal of organic and inorganic pollutants, sustainability, adsorption cycles, material reuse, and the development of new adsorbents. This study provides a systematic and objective view of research trends related to adsorption, which is expected to be a reference for researchers and practitioners to understand the development and future direction of research in this field.
