Figure 7.

Wavelength dependence of acetone evolution from isopropanol photodegradation on the cutoff wavelength of incident light, and UV–Vis diffuse reflectance spectrum of PbSnO3samples. The inset shows the wavelength dependence of light intensity with different cutoff filters (catalyst: 0.1 g, 300 W Xe lamp, 400 nm < λ < 500 nm)
