Silicone Nanofilament-Supported Mixed Nickel-Metal Oxides for Alkaline Water Electrolysis


Abbott, Daniel F; Meier, Margrith; Meseck, Georg R; Fabbri, Emiliana; Seeger, Stefan; Schmidt, Thomas J (2017). Silicone Nanofilament-Supported Mixed Nickel-Metal Oxides for Alkaline Water Electrolysis. Journal of the Electrochemical Society, 164(4):F203-F208.

Abstract

Mixed transitionmetal nickel oxide materials (M-NiO; M=Co, Mn, Fe) supported on silicone nanofilaments (SNFs) were synthesized via precipitation reaction with urea. All materials were evaluated for their OER activity in 0.1 M KOH, of which the Fe-NiO/SNFs showed a notable improvement over NiO/SNFs and unsupported NiO. The results presented herein demonstrate the extension of our previously reported synthesis for NiO/SNFs to yield SNF-supported mixed transition metal-oxide materials. The versatility and scalability of the synthesis are particularly interesting for the facile preparation of three-dimensional, binderless electrodes for alkaline water electrolysis applications.
