Structural and optical characterizations were performed using ATG (Thermogravimetric Analysis), XRD (X-ray diffraction), FTIR (Fourier transform infrared spectroscopy), DRS (Diffuse reflectance), SEM–EDX (scanning electron microscopy with energy-dispersive X-ray spectroscopy), and XPS (X-ray photoelectron spectroscopy). XRD patterns confirmed the formation of pure spinel phases at 850 °C, with crystallite sizes of 31 nm for CaFe₂O₄ and 27 nm for CoFe₂O₄. SEM images revealed relatively uniform grains with moderate porosity, while EDX confirmed high purity of materials without detectable contaminants. The optical band gaps derived from diffuse reflectance spectra were estimated at 1.85 eV and 1.27 eV for CaFe₂O₄ and CoFe₂O₄. XPS analysis identified Fe(III), O, Ca(II), and Co(II) species on the photocatalyst surfaces. Photocatalytic evaluation demonstrated efficient hydrogen evolution, reaching 396.56 µmol g⁻¹ h⁻¹ with CaFe₂O₄ at pH ~ 7 and 50 °C, and 195.33 µmol g⁻¹ h⁻¹ with CoFe₂O₄ at pH ~ 12 after 30 min of irradiation. The influence of pH, hole scavengers, and photocatalyst recyclability was also examined. The inclusion of hole scavengers results in a significant enhancement in hydrogen evolution, 660 µmol g⁻¹ h⁻¹ (78.59%) for CaFe₂O₄ and 588 µmol g⁻¹ h⁻¹ (124%) for CoFe₂O₄. The photocatalysts exhibited good stability over three successive cycles. These results highlight the potential of CaFe₂O₄ and CoFe₂O₄ as efficient photocatalysts for sustainable hydrogen production under visible light.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":750,"journal":{"name":"Reaction Kinetics, Mechanisms and Catalysis","volume":"139 2","pages":"1133 - 1150"},"PeriodicalIF":1.7,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its industrial relevance, kinetic information for this process under real operating conditions remains limited. This study uses industrial plant data to identify reaction kinetics under real operating conditions. Two data-driven kinetic identification methods were evaluated using 41 industrial trials: global vector field reconstruction and direct derivative modeling. The direct derivative approach successfully reproduced concentration trajectories and time derivatives in 32 trials (78%), achieving an average coefficient of determination of <span>(R^2 = 0.9750 pm 0.0349)</span>, while global reconstruction showed lower robustness and higher variability. Phase-space dimensionality analysis indicated predominantly three-dimensional dynamics, consistent with the coupled behavior of NaOH, <span>(hbox {H}_{2}hbox {S})</span>, and mercaptans. Spectral analysis confirmed monotonic, irreversible kinetics under plant conditions. The recovered rate expressions contain a dominant positive quadratic term, supporting an autocatalytic inhibition reaction mechanism. This study demonstrates that kinetic expression can be obtained directly from industrial operational data without laboratory experiments or additional instrumentation. The proposed methodology relies solely on routinely collected operational data and is readily applicable at industrial scale.

For the modeling phase, three key operational parameters treatment time (30–60 min), current density (4–30 mA/cm²), and inter-electrode distance (1–5 cm) were analyzed using Response Surface Methodology (RSM) based on a Box–Behnken design. Pareto graphical analysis revealed that current density was the most influential factor, followed by treatment time and inter-electrode distance. The developed quadratic models were statistically significant (p &lt; 0.05) and showed excellent agreement between experimental and predicted results. The optimal conditions (treatment time = 45.15 min, current density = 30 mA/cm², inter-electrode distance = 2.66 cm) yielded complete removal efficiencies for turbidity and TSS, and 99.6% for COD. Under these conditions, COD, BOD₅, TSS, and oil &amp; grease concentrations were drastically reduced to 3, 1.2, 1.1, and 2 mg/L, while heavy metals (Pb, Cr³⁺, Cr⁶⁺) were removed to environmentally acceptable levels.
