▎ 摘　　要

NOVELTY - High-throughput laser synthesis method of graphene loaded nanoparticles comprises (i) carrying out in-situ conversion polyimide polymer film or polyethyleneimine polymer film by laser for the first time to obtain a graphene substrate and (ii) then dropping metal precursor salt solution to the graphene substrate and drying, and laser-forming for the second time after drying. USE - The graphene-loaded nanoparticles is useful as anode material of the Li-CO2 battery (claimed). ADVANTAGE - The method: can obtain the graphene-loaded nanoparticles with high catalytic activity in a very short time (0-5 ms), and has the advantages of high-throughput large-scale preparation and highly adjustable composition; can simultaneously prepare a number of materials because of the diversity of the precursor material selection, and laser scribing, so it has the advantage of high throughput and large-scale preparation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use method of the graphene-loaded nanoparticles as the anode material of the lithium carbon dioxide (Li-CO2) battery.
