A review on emerging composite materials for cesium adsorption and environmental remediation on the latest decade

Considering the urgency of removing hazardous radioactive Cs-137, Cs+ adsorption and environmental re mediation from aqueous solutions has been given widespread concern. Composite materials (CMs) have recently emerged with good potential application in Cs+ adsorption. Herein, recent developments in the field of Cs+ adsorption covering the synthesis and performance of composite materials are reviewed. This is followed by a preliminary summary for composite materials and their further prospects in Cs+ adsorption. Based on the scope of the core and supporting materials, composite materials are classified into several categories. Along this line, the representative composite materials are introduced in view of synthesis methods and adsorption performance. Moreover, some emerging novel materials are also briefly described. Overall, this review intends to provide a preliminary database for composite materials and further guide the exploration and design of more composite materials with excellent adsorption performance in respective fields of radioactive contamination, wastewater treatment and radioisotope recycling.
