Engineering a Co/Co2P Mott–Schottky heterostructure encased in a hollow N-doped carbon polyhedron as an advanced nanoreactor towards high-efficiency electrocatalytic oxygen evolution

Through a feasible self-sacrificial template method, a nanoreactor composed of Co/Co 2 P heterostructured nanoparticles in situ confined in N-doped carbon hollow rhombic dodecahedrons (Co/Co 2 P@N-CHRDs) was designed as an excellent OER electrocatalyst.
