Abstract

With a great specific surface area, high porosity, and strong adsorption capacity, biochar has been widely applied in environmental remediation, soil improvement, and carbon sequestration. The high temperature pyrolysis process can reduce the number of functional groups of biochar and its adsorption capacity for some contaminants. Moreover, the biochar prepared by traditional methods is limited by difficulties with solid-liquid separation. Therefore, efforts have been made to enhance the physicochemical and adsorption properties of biochar through preparing modified biochar, and its application in environmental remediation has received widespread attention in academia and industry. However, there are few reviews on the preparation of modified biochar and its application in soil and water remediation. This review systematically analyses recent literatures on modified biochar, summarizes the methods of biochar modification, and briefly discusses the application of modified biochar in soil and wastewater remediation. The advances of magnetic biochar as an adsorbent and catalyst in wastewater treatment are discussed in detail. Key points and research directions on biochar composites are proposed as a reference for the massive application of biochar in the future.
