Two‐Dimensional–Layered Zn (II) Cyclophosphazene—Organic Framework for Effective Photocatalytic Removal of Organic Dyes

Applied Organometallic Chemistry, Journal Year: 2025, Volume and Issue: 39(4)

Published: March 5, 2025

ABSTRACT A novel two‐dimensional (2D) coordination polymer, formulated as {[Zn₂(trp)₂(L)]·DMF·3H₂O} ( PCP‐10 ), was synthesized via cyclophosphazene‐based tetracarboxylate H 4 L ) and N‐donor terpyridine ligand (trp). The synthesis achieved through solvothermal methods, the structure underwent thorough characterization using techniques such FT‐IR, single crystal powder XRD (SC PXRD), thermal analysis, zeta potential, UV‐DRS. X‐ray crystallographic analysis revealed that cyclotriphosphazene coordinated with Zn (II) ions, forming a 2D sheet‐like structure. Remarkably, exhibited good efficacy in degrading various organic dyes MB, MO, RhB under UVA light exposure, achieving degradation rates of up to 90%. High performance attributed unique its band gap properties. Additionally, study elucidated role reactive oxygen species (ROS) dye degradation, emphasizing significance superoxide radicals (O 2 ˙ − ). Scavenger experiments identified specific ROS involved mechanism, aiding customizing photocatalyst scavenger systems. Furthermore, durability assessed repeated use testing, showcasing high initial efficiency minimal decline over five cycles, indicative superior durability. In conclusion, this underscores potential an effective for environmental remediation, highlighting importance chemical composition structural properties optimizing photocatalytic performance. solid‐state photoluminescence were also studied.

Visible-Light Photocatalytic Activity of a ZnO-Loaded Isoreticular Metal-Organic Framework

Molecules, Journal Year: 2025, Volume and Issue: 30(6), P. 1375 - 1375

Published: March 19, 2025

A hybrid material composed of IRMOF-3 and ZnO (IRMOF-3/ZnO) was synthesized to enhance photocatalytic methylene blue (MB) degradation under visible-light irradiation. Scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, diffuse-reflectance UV-Vis analyses confirmed the successful integration into framework. Compared with unmodified IRMOF-3, demonstrated superior MB decomposition, as evidenced by faster reaction rate constants shorter half-lives. Monitoring absorbance at 670 nm (λmax) revealed more pronounced colorant removal when IRMOF-3/ZnO exposed a source. Diffuse-reflectance spectroscopy showed that has band gap 2.7 eV, whereas exhibits slightly higher 2.8 eV. This modest shift, coupled strong interaction between semiconductor MOF’s amine functionalities, enabled two distinct energy-transfer pathways: intermolecular transfer from linkers (acting antennas) ZnO, intramolecular Zn IRMOF-3. Together, these pathways generated abundant free radicals for efficient dye degradation. Despite necessity careful synthesis protocols control operating conditions preserve MOF structure optimize loading, shows promise robust, cost-effective photocatalyst water-pollutant remediation, taking advantage visible region solar light.

Comparison of the Effects of Brominated Perylenediimide and Perylene Tetraester Modified G‐C₃N₄ S‐Scheme Nanocomposites on the Photocatalytic Degradation of Anionic and Cationic Dyes and Herbicide

Global Challenges, Journal Year: 2025, Volume and Issue: unknown

Published: April 27, 2025

Abstract Metal‐free g‐C 3 N 4 (graphitic carbon nitride) is a promising candidate for the next‐generation visible light‐responsive photocatalyst; however, recombination and transfer of photogenerated charge carriers restrict its photocatalytic performances. The exfoliated g‐C₃N₄ sensitized with brominated perylenediimide (dBrPDI) perylene tetraester (dBrPTE) enhances performance due to improved separation, light absorption, and, thereby, overall efficiency in pollutant degradation. /dBrPTE hybrid composite exhibits fastest degradation against rhodamine B (RhB) pollutants. degrades RhB 2.34‐fold improvement over pure , while /dBrPDI 1.56‐fold increase . g‐C3N4/dBrPDI shows highest methyl orange (MO) MO 2.25‐fold 1.8‐fold Unlike RhB, dye sensitization does not enhance 2,4‐dichloro phenoxy acetic acid (2,4‐D) no sustained observed. Overall, these results suggest that depends only on photocatalyst material but also interaction between chemical ionic properties pollutants aquatic media.
