摘要：

A three-dimensional framework promoter of graphene-MnO2 was fabricated to enhance the catalytic properties of NiCo2O4. The as-resultant graphene-MnO2-NiCo2O4 hybrid material features a number of remarkable structural properties such as well-developed pores, 3D conductive networks and strong coupling synergistic effects, rendering it an outstanding catalyst for electrocatalytic oxygen evolution.
