water remediation

Abstract As a carbon-rich material produced by pyrolysis of biomass, biochar features low cost, large specific surface area, and widely available feedstocks based on the functional diversity and environmental-friendly properties, it has received increasing attention in the fields of pollutant removal due to three win–win effects of water remediation, carbon sequestration and reutilization of wastes.

Abstract Biochar (BC)-supported graphene-encapsulated zero-valent iron nanoparticle composites (BC-G@Fe0) are promising engineering nanocomposites that can be used to scavenge heavy metal from wastewater. However, the production of BC-G@Fe0 through carbothermal reduction using biomass as a carbon source remains challenging because of biomass pyrolysis complications. Here, we examined two carbothermal reduction routes for preparing BC-G@Fe0 using bamboo as […]

Abstract Biochar (BC) has exhibited a great potential to remove water contaminants due to its wide availability of raw materials, high surface area, developed pore structure, and low cost. However, the application of BC for water remediation has many limitations. Driven by the intense desire of overcoming unfavorable factors, a growing number of researchers have […]
