Biochar-Based Nanocomposites for Environmental Remediation

Résumé fourni par la source

Biochar (BC) stands out as a remarkable material in the domain of environmental remediation. Waste biomass, like municipal solid waste, manure, wood chips, and agricultural residues, undergo pyrolysis in a controlled oxygen environment, producing BC with a carbonaceous composition ranging from 65% to 90%. Using metal nanoparticles (MNPs) to reinforce BC significantly increases its novelty. The synergistic advantages of BC, coupled with the enhanced catalytic activity of NPs, enhance physicochemical characteristics such as thermal stability, ideal pore size, surface area, and versatile functionalization. These attributes contribute to effectively addressing emerging environmental pollution challenges and their remediation. There are three major hazards in industrial wastewater: dyes, heavy metals, and pharmaceutical compounds. Thus, BC-based Nanocomposites (BNCs) are being investigated as a potential solution for wastewater pollution treatment that uses both adsorption and photocatalytic degradation. As a result of these composites, four integrated objectives can be achieved: the removal of pollutants, waste management, carbon sequestration, and energy production. It stands as a superior choice to conventional methods, marked by cost-effectiveness, sustainability, and environmental friendliness. This chapter provides a comprehensive insight into BC-based composite with precise preparation techniques, efficacy in eliminating pollutants, and underlying adsorption processes.
