摘要: A simple ionic liquid-assisted approach for the fabrication of graphene-based nanocomposite is reported. Pd–CuO/rGO and Au–CuO/rGO nanocomposites are successfully fabricated with assistance liquid 1-butyl-3-methyl imidazolium tetrafluoroborate. The physicochemical features systematically characterized by XRD, FT-IR, Raman spectroscopy, XPS, TGA, FESEM, AFM, HRTEM. Carbon monoxide has been used as a probe molecule to emphasize performance materials. results indicate that incorporation little quantity in creation uniformly dispersed NPs simultaneously reduction graphene oxide (GO) into rGO, which leads low-temperature CO oxidation process. Besides, catalyst achieved excellent durability 14 h, without detectable deactivation. was mainly induced synergistic effects between components catalysts. Au or Pd CuO combination not only generates more interfaces, favorable activation oxygen but also enhances behavior. Consequently, composite can be considered potential candidate.
