Abstract
A method of synthesizing a three-dimensional (3D) reduced graphene oxide (RGO) foam embedded with water-splitting nanocatalysts includes providing at least one solution containing at least one precursor of nanocatalysts, and a graphene oxide (GO) aqueous suspension; mixing the GO aqueous suspension with the at least one solution to form a mixture suspension; and performing hydrothermal reaction in the mixture suspension to form a 3D RGO foam embedded with the nanocatalysts.
Claims7
A method of synthesizing a three-dimensional (3D) reduced graphene oxide (RGO) foam embedded with nanocatalysts, comprising:
- providing at least one solution containing at least one precursor of nanocatalysts, and a graphene oxide (GO) aqueous suspension;
- wherein the at least one solution comprises a first solution containing nickel (II) nitrate, and a second solution containing iron (Ill) nitrate, and the first and second solution are formed by dissolving Ni(NO3)2·6H2O and Fe(NO3)3·9H2O into deionized water respectively;
- mixing the GO aqueous suspension with the at least one solution to form a mixture suspension wherein the mixture suspension is characterized with pH=3.5 and a molar ratio of C:Ni:
- Fe=14:1:0.33;
- and
- performing one-pot hydrothermal reaction in the mixture suspension at a given pH to form a 3D RGO foam embedded with the nanocatalysts
- wherein the 3D RGO foam embedded with the nanocatalysts comprises pores that are connected to each other to form an interconnected 3D porous network of RGO sheets on which the nanocatalysts are grown.
