▎ 摘  要

NOVELTY - Synthesizing a three-dimensional (3D) reduced graphene oxide (RGO) foam embedded with nanocatalysts comprises: 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. USE - The method is useful for synthesizing 3D RGO foam which is useful in device for water splitting (all claimed) nanocatalysts for hydrogen and oxygen production. ADVANTAGE - The method provides: one-pot growth of 3D reduced graphene oxide foams embedded with water splitting nanocatalysts for hydrogen and oxygen production; and low-cost, highly stable, low-over potential and high earth abundant electrocatalysts. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a 3D RGO foam embedded with nanocatalysts, synthesized according to the method; and (2) a device for water splitting, comprising a working electrode containing 3D RGO foams embedded with nanocatalysts, synthesized according to the method.
