Templated synthesis of a bifunctional Janus graphene for enhanced enrichment of both organic and inorganic targets

We report the synthesis of a bifunctional Janus graphene with silica microspheres as a template. The two sides of the Janus graphene are asymmetrically functionalized with ethylenediamine tetraacetic acid and octadecyl groups, making it capable of simultaneous enrichment of organic and inorganic targets in complex media. This work reveals a new route to design and fabricate multipurpose adsorbent materials. We report the templated-directed synthesis of a bifunctional Janus graphene capable of simultaneous enrichment of organic and inorganic targets in complex media.
