Effective photocatalytic H2O2 generation by triphenylamine-based two-dimensional zirconium–organic frameworks

Abstract

Two triphenylamine-based layer MOFs, Zr-TCA (H₃TCA = 4,4′,4′′-tricarboxyl triphenylamine) and Zr-NBC (H₃NBC = 4′,4′′′,4′′′′′-nitrilotris-([1,1′-biphenyl]-4-carboxylic acid) were constructed for photogeneration of H₂O₂. Experiments showed that both of them exhibit high performance, which could be attributed to the abundant exposed active sites of their 2D structures.
