Cobalt Oxygen-evolving Catalysts Generated in Situ and Interfaced with Silicon-based Semiconductors for Solar Water Splitting
Abstract:
Due to the earth-abundance and prevalence in photovoltaic industries,silicon was used as lightharvesting material to from a composite with amorphous cobalt oxides oxygen-evolving catalyst(OEC) to carry out the solar-driven water-splitting in near-neutral conditions for hydrogen production.The device can efficiently utilize the solar spectrum for the photon-charge conversion and allow water splitting.The Co-OEC prepared by electrolysis deposition for 400 s exhibits excellent oxygen evolution properties,with a current density of 1.7×10-2A/cm-2 and a oxygen evolution rate of 1.28 mol/(h·m-2) in the potassium tetraborate buffer solution(pH=9.2) at 0V vs.NHE under AM1.5 simulated sunlight.
