Determination of the photoelectrochemical properties. a Linear Sweep Voltammetry curves of the optimum and reference samples. b Comparison charge of the photocurrent density under the 1.23 V vs. RHE condition. c Results of incident photon-to-current efficiency measurement under 1.23 V vs. RHE condition. d Nyquist plots, obtained by electrochemical impedance spectroscopy, showing the charge transfer resistance of each sample. e Plot of the carrier concentration calculated by fitting the Mott-Schottky plots of each sample. Mott-Schottky plots of each sample also displayed as the inset image. f Chronoamperometric measurement at 1.23 V vs. RHE for 100 h
