Anti-Kasha's rule for semiconductor photocatalytic reactions: the wavelength dependence of quantum efficiency

Abstract

We reported the wavelength-dependent quantum efficiency phenomenon for the PCET reactions between alcohol and ^tBu₃ArO˙ photocatalyzed by CdS or In₂O₃ for the first time. The excess energy beyond the lowest excited state energy level from incident photons can be introduced into the heterogeneous reaction, resulting in a significant impact on the kinetic rate.
