WebJun 15, 2024 · However, in this work, we demonstrated that dynamic halogen defects generated by the same process in bismuth oxyhalide (Bi 5 O 7 Cl) materials can act as active sites to promote charge separation and photocatalytic efficiency. WebNotably, whereas the weak interaction between the surface of bismuth oxyhalide and N 2 molecules makes it difficult for N 2 to be chemically adsorbed, the OVs generated by the cleavage of the Bi O bond greatly facilitate the adsorption of N 2 and increase the yield of N 2 conversion to NH 3.
