Figure 4. Photocatalytic performance of BCN-30.

Figure 4

(a) Stable hydrogen evolution from water by BCN-30 under visible light. The reaction was continued for 104 h, with evacuation every 20 h (dashed line). (b) Time courses of oxygen production from water by Ni-Co LDHs/BCN-30 under visible light illumination (λ>420 nm). (c) Time conversion plot for photocatalytic CO2 reduction. The amount of CO and H2 produced from the CO2 conversion system as a function of reaction time under visible light illumination (λ>420 nm). Selectivity=nCO/n(CO+H2) × 100%.
