X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), UV–vis spectroscopy, and other techniques were utilized to characterize the structural, morphological, textural, compositional, and optical properties of the composites. The prepared photocatalysts, designated as X-CdS/Mn-MOF (where <i>X</i> = 50, 25, and 10, represents the mass percentage of CdS), were tested for photocatalytic performance. Among them, the 50-CdS/Mn-MOF sample exhibits the optimized degradation efficiency of 99.1% for Rhodamine B (RhB, 20 mg/L) in 50 min under visible light irradiation, which is 7.3 times and 2.4 times higher than that of Mn-MOF and CdS, respectively. Various test results indicate that the improved photocatalytic activity of CdS/Mn-MOF composites can be attributed to the formation of heterojunctions. Specifically, the heterojunctions enhance the separation efficiency of photogenerated carriers and effectively suppress the recombination of electrons and holes, thereby improving the overall efficiency of the photocatalytic reaction. Moreover, the presence of heterojunctions optimizes the material's band structure, facilitating more efficient carrier transport, which further enhances photodegradation performance. Radical quenching experiments confirmed hydroxyl radicals (·OH<sup>−</sup>) and superoxide radical anions (·O<sub>2</sub><sup>−</sup>) played dominant roles in the photodegradation process. Additionally, the composite material also demonstrates good stability and reproducibility.

Developing an economically feasible catalytic method to facilitate the effective removal of chlorinated aromatic pollutants is critical for contamination prevention. The current study extensively investigated the utilization of organic ligands such as citrate (CA) and ethylenediaminetetraacetic acid (EDTA) to increase Fe(II)-activated persulfate (PS) for 4-chlorophenol (4-CP) and 3-chlorobenzoic acid (3-CB) degradation in water. The decomposition and consumption ability of persulfate in PS alone and Fe(II)/PS systems for 4-CP and 3-CB was very low because of the rapid utilization as well as discontinuous availability of Fe(II), which indicates the decline of Fe(III) to Fe(II). But, when using the citrate/Fe(II)/PS and EDTA/Fe(II)/PS combinations, the degradation of 4-CP and 3-CB was 78.86%, 75.01% and 84.84%, 80.99% within 30 min, respectively. The significant enhancement is due to both ligand-to-metal transfer of charges process, and this increased the process of rate determination through carrying electrons into the citrate and EDTA ligands to Fe(III), generating Fe(II). In addition, the 4-CP and 3-CB degradation facilitated with citrate/Fe(II)/PS and EDTA/Fe(II)/PS systems was efficiently degraded at acidic pH (2.0–6.0) conditions. The pseudo-first-order kinetics model accurately predicted 4-CP and 3-CB degradation in the organic ligand/Fe(II)/PS systems. The degradation percentage of 4-CP and 3-CB increased with increasing PS and Fe(II) concentrations. Moreover, both sulfate and hydroxyl radicals formed by citrate/Fe(II)/PS and EDTA/Fe(II)/PS systems were identified as major reactive oxygen species for 4-CP and 3-CB decomposition.
