Sulfur-nitrogen co-doped graphene supported cobalt-nickel sulfide rGO@SN-CoNi2S4 as highly efficient bifunctional catalysts for hydrogen/oxygen evolution reactions
文献摘要:
Designing highly active and stable electrocata-lysts for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)is a challenge for energy con-version and storage technology.In this work,a S and N co-doped graphene supported cobalt-nickel sulfide composite catalyst(rGO@SN-CoNi2S4)was synthesized simply via a one-step hydrothermal method.The as-synthesized CoNi2S4 particles grew in a mosaic manner inside GO lamellae and were encapsulated with graphene.As a bifunctional catalyst,the rGO@SN-CoNi2S4 exhibits excellent electrocatalytic performance under alkaline con-ditions,which only required the overpotential of 142.6 mV(vs.RHE)and 310 mV(vs.RHE)to deliver a current density of 10 mA·cm-2 for HER and OER,respectively.The good hydrophilicity of the rGO@SN,the pure phase of bimetallic structure,and the chemical coupling/interaction between the CoNi2S4 and the rGO@SN are attributable to be the possible reasons responsible for the higher HER and OER catalytic activities.Additionally,the rGO@SN-CoNi2S4 also shows a great potential for serving as an excellent cathode and anode electrolyzer during the water splitting process.
