▎ 摘　　要

NOVELTY - Nano-organic catalyst comprising a graphene nano-sheet framework with pyridine group, is new. Organic ligands of the pyridine group are connected by chemical methods with a transition metal ion coordinated to form the nano-organic catalyst. USE - The nano-organic catalyst is useful for oxidizing alcohol such as 1-ethanol (all claimed). ADVANTAGE - The nano-organic catalyst has good catalytic activity, and can be simply prepared with high yield. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparing the nano-organic catalyst; and (2) use of the catalyst for oxidizing alcohol.
