Figure 6. (a) Comparison of the photocatalytic CO2 conversion performance of the CN/OVs-BWO with different CN loading contents for CO production. (b) Comparison of the photocatalytic CO2 conversion performance of the CN, BWO, OVs-BWO and CN/OVs-BWO for CO production. (c) Comparison of the photocatalytic CO2 conversion of the 40%CN/OVs-BWO with the previously reported photocatalysts. (d) Recycling photocatalytic CO2 conversion tests over CN, OVs-BWO and CN/OVs-BWO. (e) CO2 photocatalytic activity under varied conditions. (f) In situ diffuse reflectance infrared Fourier transform spectra for photocatalytic CO2 conversion over 40%CN/OVs-BWO.
