Antibiotic residues have been found to have potentially harmful effects on ecological and human health. Carbon nitride-based photocatalysts have widely focused on antibiotic photocatalytic degradation. Herein, we prepared Fe-modified g-C3N4 nanorod bunches (FCNBs) using chemical vapor co-deposition. Specifically, through the process of calcination, a blend of urea and chlorophyllin sodium iron salt underwent an intriguing transformation, resulting in the integration of Fe into the framework of the g-C3N4 nanorod cluster. The resulting photocatalyst exhibited remarkable stability and superior dispersibility. The prepared FCNBs had a unique structure, which was beneficial for increasing light absorption. Furthermore, the Fe species formed a chemical coordination with the g-C3N4 matrix, thereby altering the electronic structure of the matrix. This modification facilitated charge transfer, prolonged the carrier lifetime, and enhanced light absorption, all of which significantly increased the photocatalytic activity. The oxytetracycline degradation efficiency of FCNBs was 82.5%, and they demonstrated outstanding stability in cycle trials. This work introduces a promising photocatalyst for the degradation of antibiotics.

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.
