Co 2 P/reduced graphene oxide nanocomposites and their multifunctional performances

Cobalt phosphide/reduced graphene oxide (Co 2 P/RGO) nanocomposites were synthesised successfully via a facile in‐situ solvothermal method. Co 2 P nanoparticles with a mean size of 80 nm anchor uniformly and firmly on the surface of RGO nanosheets, which not only avoid the aggregation of Co 2 P nanoparticles, but also prevent the restacking of RGO nanosheets. Used as a degradation agent, the as‐prepared composites exhibit superior adsorption degradation activity for various organic dyes. As an anode material for Li‐ion battery, the Co 2 P/RGO composites also show good electrochemical properties and its initial discharge specific capacity of the as‐prepared composites can achieve to 900 mAh/g. The reason might be attributed to the interfacial interaction and the effective combination of Co 2 P nanoparticles with RGO nanosheets.
