Synthesis of sandwich-like Mn3O4@reduced graphene oxide nano-composites via modified Hummers' method and its application as uranyl adsorbents

Synthesis of sandwich-like Mn3O4@reduced graphene oxide nano-composites via modified Hummers' method and its application as uranyl adsorbents

Efficient and sustainable remediation technologies for uranium have recently been gaining more and more interest. Adsorption techniques are facile, effective and universal for kinds of heavy metal ions. In this paper, sandwich-like Mn3O4@reduced graphene oxide (Mn3O4@G) nano-composites were prepared...
