▎ 摘　　要

NOVELTY - The catalyst has a substrate material. The metal atoms are loaded on the substrate material, and the metal atoms are coordinated with nitrogen atoms to form a catalytic active center. The metal atom is selected from transition metal atoms. The transition metal atoms are selected from non-noble transition metal atoms. The transition metal atom is selected from at least one of iron, cobalt, nickel, copper, or zinc. The substrate material is a conductive substrate material. The conductive base material comprises a conductive carbon material. The conductive carbon material comprises conductive carbon black, acetylene black, graphene, graphdine, and carbon nanotubes. USE - Catalyst for electro-catalysis carbon dioxide reduction (claimed) used for large-scale industrial synthesis and application. ADVANTAGE - The catalyst has excellent performance of electro-catalysis carbon dioxide reduction, no liquid phase product, single product, easy collection and enrichment, large current density, high unit yield, excellent catalytic performance and stable material. The catalyst synthesis is more convenient, the cost is low, and the catalytic effect of the catalyst is more excellent, better stability, suitable for large-scale industrial synthesis and application, more suitable for actual production and use, reducing the emission of carbon dioxide in the atmosphere, it can generate more ecological and social economic benefits. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing catalyst.. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a complex, in which capital letters represent elements, and numbers and lowercase letters represent atomic number numbers. (Drawing includes non-English language text).
