The UV-Vis absorbance spectra were registered with the UV-VIS Spectrophotometer, SHIMADZU UV-2600, in the wavelength range of 300–800 nm equipped with an integrating sphere. The baseline was determined with barium sulfate as reference, the scanning speed was 250 nm/min at room temperature. The...
As it can be observed, BiPO4 only can absorb UV light, in which absorbance region is from 256 to 368 nm. However, for pure g-C3N4 and Bi-CN samples, strong absorption in the visible region can appear and Bi-CN samples exhibit an absorption edge of 571 nm together with an increased ...
Figure 7. (a) UV–Vis absorbance spectrum and (b) Tauc plot of Ir-doped TiO2TiO2 and pristine TiO2TiO2. The air containing 1901 mg/m3 toluene was pumped through the system to determine the photocatalytic activity of the photocatalysts having different iridium concentrations (0.5, 1.0 and 1.5...

where A is the absorbance, R is the reflectivity, E is the band gap energy and λ is the optical wavelength. The band gap energy diagram of the sample is obtained by using (F(R)*E)1/2as the longitudinal coordinate and E as the transverse coordinate, as shown inFigure 8b. The linear...
