Hydrothermal Synthesis of Nitrogen-Doped Titanium Dioxide and Evaluation of Its Visible Light Photocatalytic Activity
Figure 9
The relation between intensity of value signal and visible light absorption of three TiO2 samples; h(ESR) refers to the signal intensity at g = 2.003, h(F(R′)) refers to the absorption intensity at 450 nm, F(R′) = (1−)2/(2), F(R′) and refer to absorptivity and reflectance at λ = 450 nm.
