Graphene oxide (GO) was functionalized by acetyl chloride to form carboxylated graphene oxide (GO-COOH). GO-COOH decorated with La particles with diameters between 0.2 and 1 μm was prepared by the sonication of a LaCl3 aqueous solution with GO-COOH. The La-decorated GO-COOH was characterized by FT-IR, TGA and TEM, and its antibacterial properties were characterized by bacteria growth kinetics. Results showed that the La3+ ions were coordinated on edges and corrugated parts of the GO-COOH by physical and chemical bonding. The La-decorated GO-COOH had a good inhibitory efficiency of 96.4% on the E.coli when its concentration was 0.5 mg/mL. It also had inhibitory effects on S.aureus and the P.Aeruginosa. The better antibacterial effect of the La-decorated GO-COOH than the corresponding La-decorated GTO was ascribed to the higher amount of La particles incorporated on the GO-COOH.
