a LSV curves and (b) the corresponding Tafel plots of L-NF (dark red) and meso-NF (gray) on Ni foam. The voltage was not iR corrected. c The spin-polarization degrees of L-NF/Ni and meso-NF/Ni measured using mCP-AFM. The error bars represent the current range of 30 samples, while the solid line data represent the average values. d LSV curves of L-NF/S-NEA 2D/3D (red), meso-NF/S-NEA 2D/3D (green), L-NF/3D (gray), and meso-NF/3D (orange) photoanodes with an active area of 0.06 cm2. e O2 generation during the PEC reaction by the L-NF/S-NEA 2D/3D and L-NF/3D photoanodesdetected using an oxygen sensor. The Faradaic efficiency of O2 generation by both photoanodes was calculated by considering the theoretical O2 generation. All of the electrochemical measurements were conducted in 0.5 M K-Pi (pH 6.5) under 1 sun illumination.
