Progress in modifications of 3D graphene-based adsorbents for environmental applications

3D graphene-based materials are promising adsorbents for environmental applications. Furthermore, increasing attention has been paid to the improvement of graphene removing pollutants. In this article, progress in modification and their performance pollutants were reviewed. The strategies, which classified as (1) activation with CO2 (steam other oxidants) (2) surface functionalization polymers (metals, metal oxides), evaluated. performances modified assessed removal waste gases (such CO2), refractory organics, heavy metals. challenges future research directions discussed applications materials.
