A graphene-MnO_2 framework as a new generation of three-dimensional oxygen evolution promoterf

摘要

A three-dimensional framework promoter of graphene-MnO_2 was fabricated to enhance the catalytic properties of NiCo_2O_4. The as-resultant graphene-MnO_2-NiCo_2O_4 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.
