Production strategies for carbon composites and carbon-based adsorbents

Abstract

Xenobiotics, hazardous compounds, and emerging contaminants contribute risk to the ecosystem, and the most effective way to reduce their harmful effects is to utilize different carbon-based composites and carbon adsorbents. Adsorption is considered a highly effective approach for eliminating pollutants. Various adsorbent materials, such as nanomaterials, natural materials, and biological biomasses, have been recognized as effective adsorbents for different contaminants. Carbon-based adsorbents are often highly flexible for cleanup because of their exceptional physical and chemical characteristics. This review presents the various forms of carbon composites as an adsorbent and their production strategies. The selection of synthesis methods and the operational parameters are found to be the key factors in determining the nature of the adsorbent and its adsorption efficiency. The pretreatment, activation, and coupling of other agents in the production of carbon composites are found to increase the adsorption efficiency of the material. The study extensively concentrated on the advancements in synthesizing carbon-sourced composites and sorbents. The research gap and the -utilization possibilities of diverse carbon composites in the removal of pollutants are also discussed.
