Figure 17. (A) Schematic illustration of the evolution of morphology and facet over NH2-MIL-125(Ti) (NMA, NMB, and NMC, where A, B, and C represent the different ratios of mixed {001} and {111} facets); (B-D) SEM images of (B) NM001, (C) NMB, and (D) NM111; (E and F) Yields of products with respect to (E) the mass and (F) the facet surface area of catalysts[132]. Copyright 2021, American Chemical Society; (G) SEM image of ultrathin nanosheets NH2-MIL-125; Comparison of (H) photocatalytic reaction rates normalized by the surface area for varied catalysts; (I) QE values of CO2 photoreduction to CH4 and CO[133].
