A novel porphyrin-doped MIL-53(Fe) photocatalyst with enhanced photocatalytic performance.

[Display omitted] • MIL-53(Fe)/TCPP was fabricated by a convenient one-pot hydrothermal method. • A ligand-regulated strategy to enhance the photocatalytic activity of MIL-53(Fe). • The incorporation of TCPP promotes photogenerated carrier transport. • MIL-53(Fe)/TCPP showed superior catalytic activity for CO 2 cycloaddition reaction. The porphyrin-doped MIL-53(Fe) (MIL-53(Fe)/TCPP) nanomaterials were constructed by a simple one-pot hydrothermal method. The properties of materials were characterized by analytical methods including XRD, SEM, FTIR, XPS, UV–vis, PL, etc. The results displayed that the MIL-53(Fe)/TCPP not only maintains the similar structural characteristics of MIL-53(Fe) but also significantly strengthens the optical performance. The optimal MIL-53(Fe)/TCPP displayed superior photocatalytic activity for the cycloaddition reaction of CO 2 with propylene oxide under visible light (λ = 460 nm) irradiation at ambient conditions, and its yield was increased by about 10 times higher than that of the original MIL-53(Fe).
