| Abstract: |
| With great specific surface area, high adsorption capacity, low cost, and strong stability, biochar has been widely applied to improve soil quality, increase soil carbon sequestration, remediate polluted environment, and reduce soil emissions of greenhouse gases. Recently, efforts have been made to enhance the adsorption capacity of biochar by preparing biochar-based composites with new properties and new structure via combining biochar with other materials physico-chemically. This review summarized the preparation, characterization, and applications of biochar and biochar-based composites. The adsorption behavior and remediation mechanisms of biochar and its composites in soil and water environment were discussed in details. Key points and research directions on biochar composites were proposed. |
