Silicon Nanowires Passivated by TiO2 Layer for Supercapacitors in Aqueous Electrolyte
Silicon nanowires(SiNWs)passivated by TiO2 have been produced and used as electrode material for supercapacitor in aqueous electrolyte.SiNWs were produced by metal-assisted chemical etching method,subsequently passivated with a TiO2 layer by a simple dripping method.The TiO2-coated SiNWs were thermal treated at 400 ℃ for 1 h in air.The capacitive properties of the electrode materials were investigated.The TiO2-coated SiNWs presented lower capacitance while higher rate capability compared to bare SiNWs in the aqueous environment.The cyclic stability of the electrode was improved significantly by the passivation of TiO2 onto the SiNWs.
