Comprehensive structural, morphological, and optical characterizations verified the successful inclusion of Fe doping and Chitosan, leading to a lowered bandgap of 2.73 eV and delayed charge carrier recombination. The average particle size was 16.1 nm, and the X-Ray Photoelectron Spectroscopy (XPS) analysis confirmed the presence of Fe in the + 3 state, which resulted in enhanced photocatalytic activity. The composite displayed excellent degradation efficiencies of 87.3% for methylene blue (MB) and 99.8% for rose bengal (RB) utilizing a low catalyst dosage and without the requirement for oxidizing agents. Scavenger investigations demonstrated the key function of hydroxyl and superoxide radicals in the photodegradation pathway. Additionally, reusability studies validated the composite’s high stability and efficiency across several cycles.

The adsorption behaviors were elucidated through a synergetic evaluation of steric and energetic factors using statistical physics equilibrium modeling. A monolayer adsorption model featuring a single energy site (R² &gt; 0.99) was employed, with parameter fitting performed via the Levenberg–Marquardt iterative method coupled with multivariable nonlinear regression. The integration of PANI nanofibers hydrogel resulted in significantly enhanced adsorption performance, achieving a maximum saturation capacity (Q_sat) of 417.5 mg/g, surpassing the capacities of PANI nanorods (Q_sat = 370.9 mg/g) and raw coal (Q_sat = 211 mg/g). The steric analysis further confirmed that PANI_(NFs)/CA exhibited the highest density of active adsorption sites (Nm = 101 mg/g), followed by PANI_(NRs)/CA (Nm = 86.3 mg/g) and raw coal (Nm = 55.9 mg/g). These findings highlight the critical role of the PANI matrix in enhancing the availability of adsorption sites, either through its inherent chemical functionality or by improving interaction interfaces. The crystalline form of PANI nanofibers hydrogel appeared to be of enhanced reactivity and surface area (48.7 m²/g) as compared to semi-crystalline or PANI nanorods. Molecular packing analysis revealed that each adsorption site in both PANI_(NFs)/CA and PANI_(NRs)/CA accommodated four 4-CL molecules, indicative of a vertical stacking arrangement and dominant multi-molecular adsorption mechanisms. These adsorption interactions were predominantly physical, as inferred from adsorption energy values (&lt; 15 kJ/mol), and proceeded spontaneously with exothermic characteristics.

Our results confirm the significant crystalline and uniform structure morphology of the designed room temperature Zn-MOFs (RZM) and hydrothermal Zn-MOFs (HZM) adsorbents. To evaluate the ability of RZM and HZM adsorbents to adsorb Congo red (CR) from an aqueous solution, numerous adsorption parameters have been studied, such as adsorbent dose, temperature, pH, contact time, and initial concentration. RZM and HZM adsorbents have been employed to assess the kinetic, thermodynamic, and isotherm models for the adsorption of CR dye under optimum removal conditions. The RZM and HZM adsorbents exhibited fast adsorption rates towards CR at pH 7, and maximal adsorption capacity according to the Langmuir model reached 200 mg g^–1 much higher value than that of other adsorbents that have been reported. The adsorption mechanisms of RZM and HZM adsorbents are based on π–π stacking and electrostatic interactions with multiple reusability. Our Zn-MOFs are synthesized using an easy, low-cost process enabling the use of affordable and easily accessible precursors. This renders the procedure cost feasible for extensive implementations. Zn-MOFs show excellent stability, with constant adsorption capabilities observed in several trials. Thorough evaluation in a range of environmental conditions has validated the repeatability of our results, assuring consistent performance.

Scherrers equation and the WH plot yield average grain sizes of 7.33 nm and 7.29 nm, respectively, for the HB-TiO₂ from P-XRD, and both methods offer reliable grain size confirmation.

Using DCF, PARA, and TC as model pollutants, degradation tests were conducted under various light sources to assess the activation of HB-TiO₂ with Fenton reagent. The outcomes showed highest degradation of DCF, PARA, and TC reaching 100% under UV 254 nm irradiation at pH 2.5 which was achieved in within 20 min, outperforming pH 7.0 and pH 10.5 after 40 min. It was proposed that HB-TiO₂ –Fenton reagent activation leads to the breakdown of contaminants. The degradation patterns of pollutants using several approaches, including Fenton’s reagent, photocatalyst (HB-TiO₂), photo Fenton catalyst and hydrogen peroxide were also examined.
