Photoresponse of Visible Light Active CM-n-TiO₂, HM-n-TiO₂, CM-n-Fe₂O₃, and CM-p-WO₃ towards Water Splitting Reaction

Figure 10

The wavelength-dependent intensity of light from a 150 W Xenon lamp at intensity of 100 mW cm⁻², measured by using silicon photon detector (UDT Sensors. Inc., Model 10DP/SB), compared to the wavelength-dependent intensity of natural global AM 1.5 sunlight in the wavelength range from 300 to 800 nm obtained from NREL website [85].
