a LSV curves performed by Si/TiO2, Si/TiO2/przpOs and Si/TiO2/trzpOs electrode in N2 and CO2 atmosphere, in 0.5 M Na2SO4 (pH 6.8 ± 0.3) solution, at scan rate of 30 mV/s, with 1.6 nmol/cm2 of [Os] complexes and without iR correction. J-t curves (b) and Faradaic efficiency (c) of Si/TiO2, Si/TiO2/przpOs and Si/TiO2/trzpOs at 0 VRHE. The Faraday efficiency was tested three times repeatedly. d GC-MS analysis of Si/TiO2/trzpOs in 0.5 M Na2SO4 (pH 6.8 ± 0.3) solution with 13CO2 and CO2, respectively.
