NOVELTY - A bimetallic nanocatalyst comprises graphene as catalyst carrier and phosphorus as doping element. The bimetallic compound is chosen from platinum and nickel, and palladium and silver. The phosphorus element is doped in bimetallic catalyst. USE - Bimetallic nanocatalyst is used for decomposing hydrogen in formic acid and hydrogen in hydrazine hydrate (all claimed). ADVANTAGE - The highly efficient bimetallic nanocatalyst is easy to recycle and prepared by simple process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of bimetallic nanocatalyst; and (2) use of bimetallic nanocatalyst for decomposing hydrogen in formic acid and hydrogen in hydrazine hydrate.
