▎ 摘　　要

NOVELTY - Preparation of graphene-coated nanoalloy catalyst, involves preparing a metal-organic ligand using 25-32 pts. wt. boron-containing polycyclic aromatic hydrocarbon and 65-74 pts. wt. transition metal acetate as raw material, adding 1-3 pts. wt. complexing agent, and uniformly adsorbing the metal ions in organic phase, adding a catalyst, carrying out low-temperature pyrolysis at 180-220 degrees C for 100-140 minutes, and carbonizing at 750-850 degrees C for 240-360 minutes. USE - Preparation of graphene-coated nanoalloy catalyst (claimed) for hydrogen production in fuel cells. ADVANTAGE - The method uses boron-doped organic phase with nano alloy to form a metal-organic ligand, which effectively protects the alloy core and improves the catalyst stability. The obtained catalyst has excellent catalytic activity with respect to hydrogen production. The method is simple, economical, and suitable for large-scale production.
