The photocatalytic H2 evolution reaction for prepared photocatalyst was carried out under the monochromate Light with 400 nm wavelength, where the measured power of light on the reaction surface was 5.00 mW/cm2 , and the irradiated area is 10 cm2 . The H2 evolution rate is 10 mol/h. Please define the apparent quantum yield (AQY) for H2 evolution, and calculate the AQY of this material at 405 nm.
