| Abstract Scope |
Porous carbon materials derived from various biomass have been extensively studied recently. Due to their unique structures, surface functional groups, and cost-effectiveness, biochars emerge as excellent eco-friendly alternatives to other adsorbents. This talk will discuss the optimization of biochars pyrolysis processes and subsequent modifications, followed by their applications in groundwater remediation and carbon dioxide capture. Surface modifications include heat treatment, composites with zero-valent nanoparticles (nZVI), and metal-organic framework (MOF), as well as alkali intercalation/acid exfoliation. These diverse modifications were designed and tailored to enhance performance to separate heavy metal ions, volatile organic compounds, and toxic organic dyes from water as well as to capture carbon dioxide molecules. Adsorption capacity and kinetics were studied using batch and column testing. Thorough characterizations allowed us to link physical and chemical characteristics to adsorption capacity and kinetics. |
