摘要: Magnetic iron oxide nanoparticles (NPs) with narrow size distribution (8 ± 2 nm), well defined chemical composition and crystalline structure are synthesized homogeneously dispersed onto the surface of few-layer graphene (FLG) via a solvothermal decomposition method. The NPs strongly anchored to confer magnetic character final composite. metal oxide/support interaction is high enough avoid coalescence and/or agglomeration thus preserve dispersion after thermal treatment up 400 °C. introduced on FLG also play role nano-spacers prevent re-stacking sheets upon drying process. It expected that such composite could find use in several application fields as catalyst support for liquid-phase reactions easy separation, electrochemical energy storage waste water treatment. ability NP/FLG adsorb foreign elements (organic pollutants) demonstrated methylene blue (MB) adsorption its catalytic properties evaluated selective oxidation H2S.
