Synthesis of a MnO2–graphene foam hybrid with controlled MnO2 particle shape and its use as a supercapacitor electrode
A simple approach was developed to synthesize the three-dimensional (3D) hybrid of manganese dioxide (MnO2) and graphene foam. The morphology of the MnO2 nanostructures can be readily controlled by the solution acidity. ...
Synthesis of graphene–carbon nanotube hybrid foam and its use as a novel three-dimensional electrode for electrochemical sensing
Three-dimensional (3D) graphene–carbon nanotube (CNT) hybrids are synthesized by two-step chemical vapor deposition (CVD) under atmospheric pressure. As revealed by scanning electron microscopy (SEM), the hybrid is a ...
Supercapacitor electrode based on three-dimensional graphene–polyaniline hybrid
Three-dimensional (3D) graphene was synthesized by chemical vapour deposition with nickel foam as a substrate. Based on the 3D graphene foams, free-standing graphene–polyaniline (PANI) hybrids were produced by in-situ ...
Hybrid structure of zinc oxide nanorods and three dimensional graphene foam for supercapacitor and electrochemical sensor applications
A hybrid structure of zinc oxide (ZnO) on three dimensional (3D) graphene foam has been synthesized by chemical vapor deposition (CVD) growth of graphene followed by a facial in situ precipitation of ZnO nanorods under ...
Superhydrophobic and superoleophilic hybrid foam of graphene and carbon nanotube for selective removal of oils or organic solvents from the surface of water
A monolithic 3D hybrid of graphene and carbon nanotube was synthesized by two-step chemical vapor deposition. Owing to its superhydrophobic and superoleophilic properties, it can selectively remove oils and organic solvents ...
