Abstract The present study explores a co‐precipitation approach for synthesizing an AC‐Cu/NiO nanocomposite and investigates its structural, optical, morphological properties. XRD analysis confirmed the cubic phase of NiO nanoparticles. measured band gap energies NiO, Cu/NiO, were 3.30, 2.97, 2.74 eV, respectively, indicating enhanced light absorption with composite formation. FE‐SEM images revealed asymmetrical, aggregated morphologies. Photocatalytic performance was evaluated through degradation Brilliant Green dye under UV light, showing efficiencies 64.34% 69.76% 90.69% after 90 min, confirming superior activity nanocomposite. Additionally, antibacterial tests against six bacterial strains demonstrated strong inhibitory effects AC‐Cu/NiO, highlighting potential environmental biomedical applications.

In present study, covalently bonded second generation of amine-terminated polyamidoamine dendrimer to silica coated magnetic nanoparticles (G2-PAMAM@SMNPs) was synthesized through step-by-step growth chemical grafting approach. Then, terminal amine groups G2-PAMAM@SMNPs were carboxylated with bromoacetic acid obtain a solid catalyst. Subsequent the prepared weakly acidic catalyst characterization, its catalytic efficiency evaluated for conversion fructose 5-hydroxymethylfurfural (5-HMF). Reaction conditions gaining an optimum yield 5-HMF from assumed and outstanding 87% afforded in dimethyl sulfoxide (DMSO)/H2O (v/v: 2/1) media at 140 ºC within 3 h. Interestingly, presence basicity character structure catalyzed isomerization glucose fructose, thus makes applicable direct as well glucose-based carbohydrates good excellent yields under same reaction dehydration. Moreover, easily recovered via separation reused six cycles without noteworthy decrease efficiency.

ABSTRACT An efficient catalytic system was developed to rapidly synthesize benzimidazole and benzothiazole derivatives under green mild conditions using MOF@MT‐COF‐Cu, which contains Zr‐Cu bimetallic sites as heterogeneous catalysts. The catalysts were characterized by powder X‐ray diffractometer (PXRD), field emission scanning electron microscope (FE‐SEM), energy‐dispersive analysis (EDS), transmission (TEM), Fourier transform infrared spectroscopy (FT‐IR), photoelectron (XPS), N 2 adsorption–desorption, thermogravimetric (TGA), inductively coupled plasma optical (ICP‐OES). prepared hybrid material has been demonstrated be an excellent catalyst because it Zr Cu combines the high specific surface area robust stability of MOF COF. In addition, exhibits several advantages, including activity, easy recovery, good repeatability, stability.
