  1. [a] Reaction conditions: 80 mg catalyst dispersed in 20 ml distilled water, visible light (λ ≥ 420 nm), room temperature, the reaction time is 4 hours; [b] Reaction conditions: 80 mg catalyst dispersed in 19 ml distilled water mixed with 1 ml methanol, other conditions as [a]; [c] pH of the solution was adjusted by con. HNO3, other conditions as [b]. [d] With the addition of AgNO3 as electron trapper, other conditions as [b]. The concentration of produced H2O2 was determined by KMnO4 titration20.
