Abstract
A method is disclosed for preparing a metal single-atom catalyst for a fuel cell including the steps of depositing metal single atoms to a nitrogen precursor powder, mixing the metal single atom-deposited nitrogen precursor powder with a carbonaceous support, and carrying out heat treatment. The step of depositing metal single atoms is carried out by sputtering, thermal evaporation, E-beam evaporation or atomic layer deposition. The method uses a relatively lower amount of chemical substances as compared to conventional methods, is eco-friendly, and can produce a single-atom catalyst at low cost. In addition, unlike conventional methods which are limited to certain metallic materials, the present method can be applied regardless of the type of metal.
