Abstract
A method of synthesizing three-dimensional (3D) reduced graphene oxide (RGO) foams embedded with water splitting nanocatalysts includes providing a first solution containing nickel (II) nitrate, a second solution containing iron (III) nitrate, and a graphene oxide (GO) aqueous suspension; mixing the GO aqueous suspension with the first solution and the second solution to form a GO-Ni—Fe mixture; adjusting a pH value of the GO-Ni—Fe mixture to be about 3.5; and performing hydrothermal reaction in the GO-Ni—Fe mixture to form RGO-Ni—Fe foams, wherein nanocatalysts containing Ni-Fi oxide particles are embedded in porous structures of the 3D RGO foams.
