The relationship between synthesis temperature and the structural and physicochemical properties of KIT-6 was elucidated through powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), nitrogen physisorption, thermogravimetric analysis (TGA), and Fourier-transform infrared spectroscopy (FT-IR). Adsorption performance was evaluated for cationic and anionic dyes. KIT-6 synthesized at 80 °C demonstrated superior capacity for cationic dyes, achieving 227 mg g<sup>−1</sup> for rhodamine B (RhB) and over 200 mg g<sup>−1</sup> for malachite green, methylene blue, and crystal violet, outperforming previously reported silica-based mesoporous materials under comparable conditions. Conversely, KIT-6 showed negligible affinity for anionic dyes (e.g., sunset yellow, quinoline yellow, methyl orange), except for congo red, which exhibited an exceptional capacity of ∼432 mg g<sup>−1</sup>, likely due to the presence of amine groups in its molecular structure. Notably, the remarkable thermal stability of KIT-6 enabled sustainable reuse of the adsorbent. The RhB-adsorbed KIT-6 was easily regenerated by combusting the adsorbate <em>via</em> a thermal treatment in air.

The challenges associated with conventional adsorption methods are articulated, leading to the introduction of a new magnetic porous three-dimensional graphene nanohybrid (MnFe<sub>2</sub>O<sub>4</sub>-3DG) for dye removal. The synthesis of three-dimensional graphene (3DG) and the MnFe<sub>2</sub>O<sub>4</sub>-3DG nanohybrid was characterized using various techniques like FTIR, SEM- EDX, EDS, TEM, XRD, BET, VSM, TGA, and UV–Vis spectroscopy. Experimental optimization is executed with Response Surface Methodology (RSM) to assess the influence of crucial parameters such as pH, contact time, temperature, initial concentration, and adsorbent dose on removal efficiency. The MnFe<sub>2</sub>O<sub>4</sub>-3DG nanohybrid, under optimal conditions such as an initial concentration of 20 mg/L, a pH of 7, a contact time of 60 min, and an adsorbent dose of 0.4 g/L, exhibits a remarkable removal efficiency of 94.15 %, thus, this result fits well with the Langmuir model (R<sup>2</sup> = 0.999), and kinetic analysis indicates a pseudo-second-order (R<sup>2</sup> = 0.999), intra particle diffusion (R<sup>2</sup> = 0.887) reactions.

Based on the findings, the MnFe<sub>2</sub>O<sub>4</sub>-3DG nanohybrid is noted as a highly effective and cost-efficient adsorbent for water purification systems.

In this study, we investigated the individual and co-immobilization of FDH and GlyDH on mesoporous silica and evaluated the addition of electrochemical NADH regeneration to improve cofactor balance. Biocatalysts were characterized in terms of immobilization efficiency, activity retention, and stability across temperature and pH ranges. We demonstrate that the optimal FDH-to-GlyDH ratio depends on whether electrochemical regeneration is applied: without it, a lower FDH/GlyDH ratio favors formate production due to GlyDH's faster kinetics; with it, a higher ratio enhances early-stage formate synthesis by alleviating NADH limitations. The system achieved a maximum DHA concentration of 17 mM (FDH/GlyDH = 1:8, no electrochemical regeneration) and a maximum formate concentration of 2.75 mM (FDH/GlyDH = 2.3:1, with electrochemical regeneration).
