The nanocatalyst was thoroughly characterised by XRD, SEM, TEM, EDX, FTIR, and VSM, confirming its nanoscale morphology, magnetic properties, and chemical composition. This polycrystalline nanocatalyst demonstrated excellent catalytic activity under mild conditions, achieving high yields of various substituted derivatives (4a, 4e, and 4 g) through a three-component condensation reaction. 1H-NMR, 13C-NMR, and Mass spectroscopy confirmed the formation of catalytic products, and the proposed mechanism was investigated. A comparative analysis with existing catalysts revealed the superior efficiency, shorter reaction times, magnetically separable, excellent reusability, and reduced environmental impact of Ni-Fe₂O₃@SiO₂-Pr-DMAP due to modification in catalyst and the elimination of harmful solvents. Additionally, the catalyst was proven recyclable, making it a cost-effective and environmentally friendly option.

Three different surfactants were utilized: the nonionic Pluronic. F-127 (F-127), the cationic Cetyl Pyridinium Bromide (CPB), and the anionic Ammonium Dodecyl Sulfate (ADS). The interactions were studied with the use of several methods, such as UV–visible spectroscopy, FTIR analysis, evaluating the zeta potential, dynamic light scattering (DLS), conductivity, fluorescence, and NMR spectroscopy. The binding constant values determined from UV-spectroscopic studies were 0.22 mM<sup>−1</sup>, 2.93 mM<sup>−1</sup>, and 0.02 mM<sup>−1</sup> for SY-ADS, SY-CPB, and SY-F-127 systems, respectively.

In comparison to ADS and F-127 surfactant systems, the conductivity, fluorescence, and 1H/13C NMR experiments also showed that SY had a stronger interaction with CPB, a higher sensitivity, and a better affinity. The in silico docking study exhibited more interactive sites in the SY-CPB combination than the other two, corroborating the experimental findings. The DLS studies displayed size enhancement in the presence of ionic surfactants and shrinking of size in the nonionic combination.

Subsequently, a co-modification process using KMnO<sub>4</sub> and KOH was employed to obtain Mn-K-DMBC, the modified biochar. Microscopic characterization revealed that the introduction of KMnO<sub>4</sub> and KOH significantly altered both the surface morphology and the pore structure of the biochar. Batch adsorption experiments demonstrated that Mn-K-DMBC exhibited a high adsorption capacity for TC, with a value of 142.58 mg/g at 308.15 K. The adsorption behavior was most effectively characterized by the Langmuir isotherm model and the pseudo-second-order kinetic model. Thermodynamic assessments demonstrated that the process was spontaneous and exhibited endothermic properties. Finally, the analysis revealed that the adsorption of TC onto Mn-K-DMBC is primarily driven by mechanisms such as pore filling, hydrogen bonding, metal complexation, and π-π interactions.

One of the most innovative parts of this research is applying doxorubicin as an expired medicinal drug to embrace the circular economy.
