▎ 摘　　要

NOVELTY - Flakes of graphene surface-modified nanoparticles composite of carbon monoxide-titanium-noble metal, is disclosed. Preparation of modified graphene flakes, comprises dispersing flakes of graphene or graphene oxide in an organic solvent comprising 3-9C aliphatic hydrocarbons, adding titanium compounds (IIa)-(IIe), and noble metal compounds (IIf), stirring in presence of dry or humid air, removing the solvent, drying the residue, and subjecting to thermal decomposition in the presence of air at 200-700 degrees C. USE - Used as flakes of graphene surface-modified nanoparticles composite of carbon monoxide-titanium-noble metal. DETAILED DESCRIPTION - Flakes of graphene surface-modified nanoparticles composite of carbon monoxide-titanium-noble metal, is disclosed. Preparation of modified graphene flakes, comprises dispersing flakes of graphene or graphene oxide in an organic solvent comprising 3-9C aliphatic hydrocarbons, adding titanium compounds of formulae (IIa)-(IIe), and noble metal compound of formulae (IIf), stirring in presence of dry or humid air, removing the solvent, drying the residue, and subjecting to thermal decomposition in the presence of air at 200-700 degrees C. The titanium compound is present in the organic solvent at 0.001-10 mole/l, and the noble metal is present in the organic solvent at 0.001-10 mole/l. R, R11 = 1-9C alkyl; n = 3-4; x, m = 3; y = not defined; and R12 = 1-9C alkyl or inorganic substituent of groups V-VII containing carbonates, hydroxides, chlorides, sulfides, fluorides, iodides, nitrates and/or thiocyanates.
