▎ 摘  要

NOVELTY - Obtaining hybrid nanomaterials comprising a two-dimensional (2D) nanomaterial with metallic nanoparticles anchored to the surface of the 2D nanomaterial, comprises:(a) adding a mixture to a container that comprises 32-33 wt.% 2D nanomaterial precursor, 65-66 wt.% exfoliating material, which is a biocompatible organic molecule, and 1-2 wt.% nanoparticle precursor material, with at least 15 balls of the same material as the container; (b) introducing the container with the mixture obtained in the step (a) into a planetary ball mill at 15-30° C, in air for 0.8-12.5 hours at a speed of 100-250 rpm; (c) dispersing the solid obtained in the step (b) in water and dialyzing the solution by heating to 60-80° ; and (d) drying the dispersion obtained in stage (c), by lyophilization at 0.001-0.020 bar. USE - The process is useful for obtaining hybrid nanomaterials. ADVANTAGE - The process is simple and environmentally friendly.
