*3.6. Scavenger Activity*

Active species capture experiments were used to study the photocatalysis mechanism. First, isopropyl alcohol (IPA; 0.5 mM) was used as the hydroxyl scavenger (•OH˙), benzoquinone (BQ; 0.5 mM) was employed as the superoxide scavenger (•O2 −), and ammonium oxalate (AO; 0.5 mM) was used as the hole scavenger (h+) [70]. Different scavengers were used in the trapping experiments to check the inhibitory effect of scavengers during the photocatalytic reaction under analogous irradiation experimental conditions.
