METHODS FOR SYNTHESIZING CARBON NANOCAGES

摘要

A method for synthesizing carbon nanocages, including N-doped carbon nanocages, includes a first step of forming a solution including a metal salt and an organic carbon source; a second step of drying the solution to obtain a precursor powder; and a third step of annealing the precursor powder to obtain a nanocage including a metal nanoparticle surrounded by a carbon shell. The metal nanoparticle is then removed from the carbon shell by applying an acid solution.
