WC and cobalt nanoparticles embedded in nitrogen-doped carbon 3D nanocage derived from H3PW12O40@ZIF-67 for photocatalytic nitrogen fixation

The 3D nanocages nitrogen-doped graphitic carbon (NGC) nanocages hybrid loaded with WC nanoparticles and Co nanoparticles (WC–Co/NGC) were first used for the nitrogen fixation.
