“…From the above presented published results ,− and discussions of the data presented by Li et al, we cannot conclude, in the present state of research, that photo-oxidation using 360 nm LED is an effective alternative aerobic oxidation methodology for benzaldehyde aerobic oxidation in water. Oxygen availability has been identified as a key factor limiting oxidation in water, and the use of inadequate glassware, i.e., a 15 mL test tube with 2 mL of water, does not allow for efficient oxygen mass transfer into the aqueous phase, making it difficult to compare with previously described methods.…”
