Regulating the Donor and Acceptor Interaction Mode in Metal-Organic Frameworks for HO Photosynthesis.

Development of novel photocatalysts for hydrogen peroxide (HO) production from water and oxygen is gathering great attention, but still suffers from inefficient photogenerated charge mobility. Reticular chemistry in metal-organic frameworks (MOFs) provides a promising platform to enhance the charge-transfer kinetics by assembling a donor-acceptor (D-A) system. Here, we designed and synthesized a series of D-A type MOFs (UiO-67-NB, UiO-67-PE/BB, and UiO-67-PE/NB) via regulating the interaction mode of donor and acceptor.
