Figure 5. A: Photocurrent density of OCN-NPs and CNTs with different weight ratios (λ ≥ 400 nm, -0.5 V vs. SCE). B: EIS Nyquist plots of OCN-NPs and CNTs with different weight ratios. C: Photocurrent density of OCN/CNTs with different acidification times (λ ≥ 400 nm, -0.5 V vs. SCE). D: EIS Nyquist plots of OCN/CNTs with different acidification times. E: PL spectra of OCN-NPs, OCN-200/CNTs-12h and OCN-200/CNTs-18h. F: Band structure alignments of OCN-NPs and OCN-200/CNTs-18h.
