A novel composite ultrafine cobalt nanoparticles-reduced graphene oxide (Co-RGO) was firstly synthesized through a modified one-step solvothermal method with Co(OH)2 as the precursor. The prepared low-cost Co-RGO composite exhibited excellent catalytic activity for the reduction of highly toxic Cr(VI) to nontoxic Cr(III) at room temperature when formic acid (HCOOH) was employed as the reductant, and...
A novel flake composite benzenoid-like CuFeO2@reduced graphene oxide (CuFeO2@RGO) was fabricated via a one-step low temperature solvothermal route. The obtained samples were characterized by XRD, FTIR, Raman, SEM, TEM and XPS, which indicated that the hexagonal CuFeO2 nanocrystals sized 150–200nm were well dispersed on the surface of the RGO sheets. For the first time, we applied such CuFeO2@RGO composite...
