Photocatalytic production of hydrogen peroxide through selective two-electron reduction of dioxygen utilizing amine-functionalized MIL-125 deposited with nickel oxide nanoparticles

Abstract

Photocatalytic H2O2 production via two-electron reduction of O2 was realized by visible-light irradiation of a metal–organic framework, MIL-125-NH2, in the presence of TEOA and benzylalcohol. Deposition of NiO nanoparticles onto MIL-125-NH2 dramatically enhanced the catalytic activity. Further studies suggested that fast disproportionation of the O2˙ intermediate to H2O2 resulted in the enhancement.
