Varied CO2 photoreduction activities of UiO-66-NH2 MOFs with different aggregation morphologies†

Abstract

Several kinds of UiO-66-NH₂ with different aggregation morphologies were prepared to verify that the morphology of the photocatalyst could influence charge transfer. That showing poor aggregation exhibits superior CO₂ photoreduction performance, attributed to the small particle size related to the poor aggregation and to the resulting high efficiency of separation of photogenerated electrons and holes.
