Generally, higher intensity light sources give greater product yields, as shown in the study of König and co-workers using a series of commercial photoreactors. From the description of the literature reaction setup, it is not possible to ascertain accurately what is the incident photon flux on the reaction vessel, a key parameter in photocatalysis. As such, it becomes difficult to compare the yields obtained in our set-up with those obtained by others, signifying the importance of replicating literature reactions in ones own set-up to enable a meaningful crosscomparison of the yields with different PCs.
