Abstract: A method for characterizing graphene on a platinum substrate, including: coating a methylene blue developing solution to a platinum substrate having a surface covered with graphene, so that the methylene blue developing solution reacts with hydrogen-containing gas under catalysis of platinum to yield colorless methylene white; after the pressure is restored, methylene white in the exposed area of platinum substrate will quickly turn blue when it is oxidized into methylene blue by reacting with oxygen in the air under catalysis of platinum. Thus, color difference can be formed to facilitate the observation of the graphene. The characterization method is highly reproducible and simple, and can be used to characterize graphene with a large area on a platinum substrate. The characterization method does not damage the graphene and platinum substrate, has no negative impact on the quality of graphene, and the platinum substrate can be recycled to reduce costs.
