Porous Carbon Adsorbents for CO2 Capture and Wastewater Dye Removal
This community develops porous carbon materials and related adsorbents to remove carbon dioxide from gas streams and to strip synthetic dyes and other pollutants from water.
The work centers on the synthesis and application of activated carbons, graphene oxide, and porous carbon composites derived from biomass or waste streams. Recurring applications include the adsorption of carbon dioxide for capture and the removal of specific dyes—such as methylene blue, congo red, and malachite green—from aqueous solutions. Methods frequently involve chemical activation, pore engineering, and the use of ionic liquids or covalent organic frameworks to enhance surface area and selectivity. The papers describe the preparation of these materials, their characterization, and their performance in removing target contaminants from liquid or gas phases.
Carbon research accounts for the largest share of this community’s output, representing 2.0% of all tracked carbon research, and contains 18,047 papers within this group. Nitrogen and hydrogen research also contribute significantly, with 3,101 and 2,375 papers respectively.
The community comprises 28,923 papers, publishing most frequently in Carbon, Chemical Engineering Journal, and Separation and Purification Technology.
Recent work continues to focus on optimizing biomass-derived activated carbons for tetracycline adsorption and low-energy CO2 capture, as well as exploring electrochemical technologies for carbon separation and the repurposing of waste plastics into dye-removing adsorbents.
