Figure 7. A-B: Cdl value calculated from CV curves and ECSA (m2/gcat) for OCN-x/CNTs and OCN-200/CNTs-y. C: Photocurrent density of OCN-NPs and OCN/CNTs measured under a saturated Ar (inset) or O2 atmosphere and visible-light illumination (λ ≥ 400 nm, V = -0.5 V vs. SCE); D: LSV of OCN-NPs and OCN/CNTs measured under a saturated Ar (inset) or O2 atmosphere with visible-light illumination (λ ≥ 400 nm, pH = 3).
