[51,101,104,107,108,123,[137][138][139][140] Less studied but equally relevant for large-scale applications are the effects of light intensity [43] and photocatalyst concentration [128] because of the possible screening effect on the bulk of the reaction media. Most researchers vary one or two factors independently to define the best combinations of factors; as ar esult, interaction effects are usually not involved in these studies.…”
