“…Figure c signifies the N 1s core-level spectra of TCPP(Fe)-Ni and Ni-TCPP nanofibers. Ni-TCPP exhibits two obvious peaks after fitting, corresponding to CN–C (398.83 eV) and C–N–C (400.33 eV) . In contrast, TCPP(Fe)-Ni shows a movement of C–N–C (400.68 eV), revealing the N atoms from the coordination between the imine group and Fe 3+ .…”

A bimetallic metal–organic framework (MOF) nanofiber TCPP(Fe)-Ni has been synthesized by a simple solvothermal method, and the ligand TCPP(Fe) has been synthesized by organic synthesis. The presence of metalloporphyrins ligands is beneficial for the transport of Li+ and electrons, which is conducive to enhancing lithium storage of the TCPP(Fe)-Ni anode. In addition, the chelating effect between the metal center Fe3+ and porphyrin will facilitate the cycle stability compared with Ni-TCPP MOF. The TCPP(Fe)-Ni material shows superior rate capability and high reversible capacity of 950 mAh g–1 at 0.1 A g–1 as an anode for lithium ion batteries (LIBs). This work provides an improved synthetic route of metalloporphyrins and a better understanding of porphyrin MOF as a high performance anode.

“…Morphological regulation of photocatalysts, which involves regulating crystal shape (1D, 2D, and 3D), size, and plane, is widely recognized as an effective approach for the enhancement of photocatalytic activity. [52,53] While literature reports on the design and preparation of various MOFs with different morphologies, such as MOF nanomaterials with different shapes that can be prepared by simple coordination modulation strategies, [54] the impact of MOF morphology on their photocatalytic activity has not been fully comprehended, and there are only a few systematic studies available on this topic. 2D MOF nanosheets have garnered a lot of attention in various MOFs due to their distinctive structural features and physicochemical properties.…”

Photocatalytic membranes can effectively integrate membrane separation and photocatalytic degradation processes to provide an eco‐friendly solution for efficient water purification. It is of great significance to develop highly efficient photocatalytic membranes driven by visible light to ensure the long‐term stability of membrane separation systems and the maximum utilization of solar energy. Metal‐organic framework (MOF) is an emerging photocatalyst with a well‐defined structure and tunable chemical properties, showing a broad application prospect in the construction of high‐performance photocatalytic membranes. Herein, this work provides a comprehensive review of recent advancements in MOF‐based photocatalytic membranes. Initially, this work outlines the main tailoring strategies that facilitate the enhancement of the photocatalytic activity of MOF‐based photocatalysts. Next, this work introduces commonly used methods for fabricating MOF‐based photocatalytic membranes. Subsequently, this work discusses the application and mechanisms of MOF‐based photocatalytic membranes toward organic pollutant degradation, metal ion removal, and membrane fouling mitigation. Finally, challenges in developing MOF‐based photocatalytic membranes and their practical applications are presented, while also pointing out future research directions toward overcoming these existing limitations.

How to improve the stability and activity of metal–organic frameworks is an attractive but challenging task in energy conversion and pollutant degradation of metal–organic frameworks materials. In this paper, we developed a facile method by fabricating TiO2 nanoparticles (NPs) layer on 2D copper tetracarboxylphenyl‐metalloporphyrin metal–organic frameworks (MOFs) with Zn2+ as the linkers (ZnTCuMT‐X, “Zn” represented Zn2+ as the linkers, the first “T” represented tetracarboxylphenyl‐metalloporphyrin (TCPP), “Cu” represented the Cu2+ coordinated into the porphyrin macrocycle, “M” represented MOFs, the second “T” represented TiO2 NPs layer, and “X” represented the added volume of n‐tetrabutyl titanate (X = 100, 200, 300 or 400)). It was found that the optimized ZnTCuMT‐200 showed greatly and stably enhanced H2 generation, which was about 28.2 times and 47.0 times as high as those of the original metalloporphyrin MOFs and TiO2, respectively. Combined with the results of free radical capture, X‐ray photoelectron spectra, electron spin resonance and theoretical calculation, a direct Z‐scheme electron transfer mechanism was achieved to fully explain the enhanced photocatalytic performance. It demonstrates that facilely designing Z‐scheme heterostructures based on porphyrin MOFs modified with inorganic semiconductor layer could be an advantageous strategy for enhancing the stability and activity of photocatalytic hydrogen evolution.
