Figure 7From: Photocatalytic Degradation of Isopropanol Over PbSnO3Nanostructures Under Visible Light IrradiationWavelength 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)Back to article page
