Abstract | Nano-level manganese oxide particles deposited on the surface of nickel foam (NF/MnOx) have a great potential in the field of electrochemical water splitting. In addition, these hierarchical Ti3C2Tx@TiO2/MoS2 powders consist of non-cubic TiO2 derived from defect sites of Ti3C2Tx and MoS2 sheets preventing inner Ti3C2Tx@TiO2 from corrosion of electrolyte covered these layered Ti3C2Tx particles accompanied with heterojunction interface and plentiful exposed active sites. In this work, the electrochemical performance of multicomponent mixed manganese oxides prepared by rapid electrodeposition is restricted by the poor electrical conductivity, but the addition of Ti3C2Tx@TiO2/MoS2 can improve the surface area to electrolyte, enhance the Faradaic reaction and reduce ion diffusion length. Thus, the NF/MnOx-Ti3C2Tx@TiO2/MoS2 sample can incorporate these electrochemical advantages of NF/MnOx and Ti3C2Tx@TiO2/MoS2. By characterization of as-prepared samples, it finds that these samples are combined amorphous phases with crystalline, so they can commonly improve the electrochemical performance by synergistic reaction. As the result of electrochemical test shown, the NF/MnOx-Ti3C2Tx@TiO2/MoS2 sample performs excellent oxygen evolution performance and possesses a low overpotential of 270 mV with the current density of 10 mA/cm(2). The stability of the NF/MnOx-Ti3C2Tx@TiO2/MoS2 sample is evaluated under 10 mA/cm(2) for 42 h and the overpotential maintains unchanged during the whole test. Thus, the NF/MnOx-Ti3C2Tx@TiO2/MoS2 sample can serve as excellent catalysts for oxygen evolution reaction. |
