▎ 摘　　要

NOVELTY - A catalyst comprises a carbon-based support, and catalytic moiety containing a metal-nitrogen bonding structure (I), and bonded to the carbon-based support. USE - Catalyst used for producing hydrogen peroxide for chemical and medical industry. ADVANTAGE - The catalyst has excellent kinetic current density, mass activity, selectivity, stability for long period of time, is manufactured economically by simple method. DETAILED DESCRIPTION - A catalyst comprises a carbon-based support, and catalytic moiety containing a metal-nitrogen bonding structure of formula: M-N (I), and bonded to the carbon-based support. M = silver transition metal. M functions as a silver metal single atom catalyst. An INDEPENDENT CLAIM is included for manufacture of the catalyst, which involves preparing a carbon-based support, providing a transition metal atom (M) to the carbon-based support, and doping nitrogen to the carbon-based support. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of illustrating manufacture of cobalt-graphene oxide.
