Boron containing metal–organic framework for highly selective photocatalytic production of H2O2 by promoting two-electron O2 reduction

The adsorption sites of boron in UiO-66-B lead to in a larger amount of O 2 adsorption; and the H + is adsorbed on the oxygen adjacent to boron, which is more conducive to the proton coupling reaction of ˙O 2 − to H 2 O 2 in the second step.
