a Photocurrent–thickness relationship of CNT electrodes. b Photocurrent density curves (chronoamperometry) of CNT electrodes at 1.23 V vs. RHE in 0.1 M KOH (blue, cyan, and magenta lines) and in 0.1 M KOH containing 10% (v/v) TEOA (red line). c IPCE plots of CNT electrode as a function of incident wavelength and UV–Vis spectrum of CNT electrode. d LSV curves of CNT electrode in 0.1 M KOH with and without light. All the light conditions are calibrated one-sun illumination. Each IPCE (%) data point represents an average of three different CNT electrodes; error bars represent standard deviation.
