摘要

The light-intensity dependence (LID) of oxygen evolution using titanium(IV) oxide particles and electron acceptors under intense UV-LED irradiation was multimodal; in general, the LID changed from second to first order, and then fourth order in some cases. Such LID-order switching could reasonably be explained using a kinetic model in which the probability of multipleelectron (positive holes) accumulation in each particle governs the overall rates digitally.
