▎ 摘　　要

NOVELTY - Graphene-two-dimensional noble metal atomic layer composite material is claimed. The composite material is prepared by depositing noble metal atom on graphene layer to form two-dimensional surface, where the noble metal atom is nano-grade metal atom, and the noble metal atom deposited vertically on the graphene layer is very thin having single-layer or double layer atom thickness. USE - The graphene-two-dimensional noble metal atomic layer composite material is useful for oxidation of methanol. ADVANTAGE - The composite material: carried out methanol oxidation at a higher catalytic activity; comprises graphene and two-dimensional noble metal atom, which has strong coupling effect; and optimizes the structure of the product and improve the performance of the product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene-two-dimensional noble metal atomic layer composite material, comprising (a) oxidizing natural graphite to form oxidized graphite, and ultrasonically dispersing graphite oxide in an aqueous solution to form graphene oxide solution, (b) slowly adding graphene oxide solution on glass electrode surface in a drop wise manner and slowly drying, (c) immersing the glass electrode into lead(II) ion solution, where electrochemical reduction converts lead(II) ion to lead(0), and (d) immersing glass electrode into noble metal ion solution, to carry out noble metal ion and lead(0), and washing the glass electrode with distilled water.
