Photocatalytic H 2 O 2 production via two-electron reduction of O 2 was realized by visible-light irradiation of a metal-organic framework, MIL-125-NH 2 , in the presence of TEOA and benzylalcohol. Deposition of NiO nanoparticles onto MIL-125-NH 2 dramatically enhanced the catalytic activity. Further studies suggested that fast disproportionation of the O 2 &z.rad; − intermediate to H 2 O 2 resulted in the enhancement. Photocatalytic H 2 O 2 production via two-electron reduction of O 2 is realized by visible-light irradiation of a Ti-based metal-organic framework, MIL-125-NH 2 .
