Figure 5. (A,B) [Ru^II(bpy)₃] encapsulated in pores of FJI-Y2 MOF (highlighted as yellow atoms) and the interactions between the FJI-Y2 MOF ligands and [Ru^II(bpy)₃] cations. (C) Cooperative catalysis mechanism of NDI radical and [Ru^II(bpy)₃] photocatalyst via a SET pathway. This figure is used with permission from Elsevier^[125]. (D) Atomic-resolution TEM image of R-WO₃ nanosheets. (E) ESR spectra of D-WO₃ and R-WO₃. (F) Simulated differential charge density for O₂ chemisorbed at a CUS W site of defective WO₃.
