A Review of Researches on Removal of Organic Pollutants in the Environment by Biochar-nanocomposites

Biochar has been widely used in environmental remediation, carbon sequestration, soil modification and etc. in recent years. Compared to the primary biochar, biochar nanocomposites, which are made from biochar and nanomaterials, have greatly improved surface area, pore structure, functional groups and ability of catalytic degradation, so they are more sustainable and efficient on removing organic pollutants. This paper introduces different preparation processes of biochar nanocomposites systematically and emphasizes the mechanism and application of biochar nanocomposites in the removal of organic pollutants in different environmental media. This work may provide some theoretical and technical supports for the engineering and commercialization of biochar nanocomposites in the field of environmental remediation in the future.
