- -/ Metal-nitrogen/carbon catalysts having metal-nitrogen ligands as active sites and methods for preparing thereof

摘要

The present invention relates to a metal-nitrogen/carbon catalyst (MN/C catalyst) having a metal-nitrogen ligand as an active site, a method for preparing the same, and a metal-air secondary battery comprising the same, and more particularly, to a carbon support with the same or different atoms It is possible to easily add homogeneous or heteroatomic functional groups into the carbon catalyst by using various organic solvents containing a carbon support and metal-nitrogen instead of depositing a metal-nitrogen ligand in an organic solvent that is a carbon support through high-temperature heat treatment. A metal-nitrogen/carbon catalyst (MN/C catalyst) having a metal-nitrogen ligand capable of synthesizing a carbon catalyst in a form in which a ligand material is covalently bonded to each other as an active site, a method for preparing the same, and a metal-air secondary battery comprising the same it's about
