In this study, a reduced graphene oxide anchored nZVI/Al hybrid (rGO@nZVI/Al) was synthesized for effective degradation of chloramphenicol (CAP) at neutral pH just through the activation of dissolved oxygen (DO). The morphology and physicochemical features of rGO@nZVI/Al were characterized with the field emission scanning electron microscopy combined with energy dispersive spectroscopy (SEM-EDS), Brunauer-Emmet-Teller surface area analysis (BET) and X-ray diffraction (XRD). The CAP removal by rGO@nZVI/Al was conducted at neutral pH, and the performance of rGO@nZVI/Al for DO activation was also estimated in view of the effect of various systems. The reusability of rGO@nZVI/Al was investigated through the cycle tests and the variation of UV spectrum for further application.

Abstract The use of metal oxides as electrode materials has seen great success in lithium-ion batteries. However, this type of electrode materials has been regarded as an improper option for rechargeable aluminium-ion batteries (AIBs) in comparison with sulfides and selenides, and has, thus, been nearly abandoned. Here, we demonstrate the suitability of metal oxides as cathode materials of AIBs, exhibiting high electrochemical activities toward Al-ion storage. We designed economical metal-oxide cathodes (Co3O4@reduced graphene oxide (rGO), Fe2O3@rGO, and CoFe2O4@rGO) for AIBs. The Co3O4@rGO displayed superior electrochemical properties, regarding both capacity and lifespan, to the current state-of-the-art cathode material reported by scientific literature. Furthermore, the CoFe2O4@rGO exhibits rational electrochemical capacities and an extremely stable charge/discharge process with an excellent Coulombic efficiency of 99.6%. The proposed study expects to stimulate researchers to focus on the overlooked metal oxides as competitive cathode materials for high performance AIBs.

Reduced graphene oxide (rGO) is a reduced form of graphene oxide used extensively in gas sensing applications. On the other hand, in its pristine form, graphene has shortages and is generally utilized in combination with other metal oxides to improve gas sensing capabilities. There are different ways of adding rGO to different metal oxides with various morphologies. This study focuses on rGO-loaded metal oxide nanofiber (NF) synthesized using an electrospinning method. Different amounts of rGO were added to the metal oxide precursors, and after electrospinning, the gas response is enhanced through different sensing mechanisms. This review paper discusses rGO-loaded metal oxide NFs gas sensors.
