AI Technical Summary
Existing nitrogen-doped carbon thin films suffer from poor adhesion to the substrate, low density of active sites, insufficient catalytic activity, and difficulty in controlling substrate surface uniformity, which affects device stability and electrocatalytic performance.
A multi-step process combining etching modification, impregnation modification, and magnetron sputtering deposition with high-temperature annealing is employed. Through the synergistic effect of electrocatalytic active modifiers, etching modifiers, and impregnation modification liquids, a uniform nanoscale rough structure is formed on the substrate surface, which enhances the bonding strength between the film and the substrate and the density of active sites, thereby achieving precise control over the composition and structure of the film.
It significantly improves the oxygen reduction catalytic activity and stability of nitrogen-doped carbon films on modified substrates, reduces catalyst costs, and facilitates industrial production.
