In this study, a modified montmorillonite based catalyst is employed for the synthesis of 2,3-dihydroisoxazolo[5,4-<i>d</i>] pyrimidin-4(7 H)-ones, which are promising candidates for anticancer agents. Montmorillonite is modified using mixed metal oxides, typically Al₂O₃ and CeO₂, by a facile approach followed by standard spectroscopic and electron microscopic characterizations. It is then employed for the one-pot synthesis of a series of 2,3-dihydroisoxazolo[5,4-<i>d</i>] pyrimidin-4(7 H)-ones. The synthesis protocol, mediated by ultrasound, is simple, efficient, and environment friendly. The mixed metal oxide pillared montmorillonite catalyst exhibits high catalytic activity and selectivity, facilitating the formation of the desired compounds in good to excellent yields. The synthesized compounds are characterized using various spectroscopic techniques such as ¹H NMR, ¹³C NMR and mass spectrometry. Furthermore, the anticancer activity of the synthesized compounds is evaluated against a series of cancer cell lines, revealing promising cytotoxic effects.

Unlike the traditional methods known for CWE treatment – fermentation, enzymatic hydrolysis, ultrafiltration, etc., aqueous-phase reforming (APR) is a technology which helps to treat the wastewater by valorising it producing high heating value gases such as hydrogen (H₂), thus achieving a double benefit. In this work, APR of lactose as a model compound from CWE was carried out using a Pt promoted Ni/Htlc catalyst (where Htlc refers to hydrotalcite) in a stirred batch reactor. Experimental trials were performed where the reaction parameters viz. temperature (488–518 K), catalyst loading (2–6 kg/m³), reaction time (1.5–6 h) and lactose concentration (1–5 wt%) were optimized. For optimized parameters, H₂ selectivity of 73% was achieved. The catalyst support Htlc was prepared using Cu and Al, the former being water gas shift (WGS) promoter. Furthermore, the effect of promotion by Pt was investigated with three different loadings (1–5%), where 2.5% Pt outperformed others. The Ni loading was fixed at 10% in all the catalysts. The synthesized catalyst was characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) analysis and Fourier transform infrared spectroscopy (FTIR).

Mg/Fe-LDH modified with <i>Moringa</i> biochar was created using in situ co-precipitation method. The synthetic LDHs were characterized using thermogravimetric analysis (TGA), field emission scan electron microscope (FE-SEM), transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS), X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) techniques for nitrogen adsorption–desorption. Experimental design techniques are employed to optimize removal efficiency by examining factors such as pH, temperature, adsorbent dosage, and contact time. The resulting LDHs exhibits improved adsorption properties due to the combined effects of Mg/Fe LDHs and the high surface area of <i>Moringa</i> biochar (S_BET increased from 87 to 144 m²/g after modification with biochar). Through response surface methodology, optimal conditions are determined to maximize NG removal and found to be pH 7.8, contact time 150 min, dose 380 mg, and temperature 25°C. With an R² value of 0.999, 0.998 and an adjusted R² value of 0.997 and 0.993 in the RSM model for Mg/Fe and Mg/Fe-BC LDH, respectively, it can be concluded that the chosen model is appropriate for data analysis (quadratic model). Additionally, the adequacy precision was assessed using the signal-to-noise ratio, which was determined to be around 23 and 66 for Mg/Fe and Mg/Fe-BC LDH, respectively (significantly higher than the baseline of 4), indicating a satisfactory signal. The highest adsorption capacity of Mg/Fe and Mg/Fe-BC LDHs was determined to be 43 and 53 mg.g⁻¹ (with removal efficiencies of 82 and 97%, respectively).
