There are many ways and means for environmental detection and environmental protection.Due to the unique physicochemical properties of graphene,more and more efficient adsorbents and sensors based on graphene and functionalized graphene are constructed for the removal and detection of environmental pollutants.This paper reviews the research results on the application of graphene-based materials in environmental protection and detection in recent years.For environmental considerations,modified graphene can adsorb heavy metal ions efficiently and selectively,and reduce them to metals for recycling.Several graphene-based high detection limit sensors for detecting heavy metal ions,toxic gases and organic pollutants in the environment are also listed.Finally,future challenges of graphene-based adsorbents and detection devices are envisioned.
