CoFe alloy nanoparticles encapsulated in a 3D honeycomb-like N-doped graphitic carbon framework for photocatalytic CO2 reduction

CoFe alloy nanoparticles (NPs) encapsulated in a three-dimensional (3D) honeycomb-like porous N-doped graphitic carbon (CoFe/N-GC) framework were fabricated by a facile polymer thermal treatment method.
