Claims14
A carrier-nanoparticle complex comprising:
- a carbon carrier having a polymer layer provided on a surface thereof;
- and
- metal nanoparticles provided on the polymer layer of the carbon carrier,
- wherein the polymer layer comprises a polyalkyleneimine, and
- a content of a nitrogen element (N) of the polymer layer is 0.5 wt % or more based on a total mass of the carbon carrier having the polymer layer.
