This paper uses a one-step synthesis method to prepare NH2-ZIF-8/NCDs porous materials. A series of composite photocatalysts were obtained by adjusting the additional amount of nitrogen-doped carbon quantum dots (NCDs). The structural characteristics of the nanocomposites were characterized using XRD, FTIR, FESEM, TEM, and BET. The photocatalytic activity of NH2-ZIF-8/NCDs nanocomposites was investigated through […]
Continued research on pyrazoline derivatives with excellent biological activities has encouraged us to design and synthesize 1,3,5-trisubstituted pyrazoline series introducing NiFe2O4.Cu(OH)2 magnetic nanocomposite as a heterogeneous catalyst by the combination of highly substituted aryl aldehydes, substituted acetophenones, and acetyl hydrazine hydrate under ultrasound irradiation at 50oC. The NiFe2O4.Cu(OH)2 magnetic nanocomposite materials are characterized by […]
This article investigates an efficient and eco-friendly protocol for protecting amines and alcohols as important molecules in organic chemistry, using Fe3O4@MCM-41/Zr@Piperazine as a newly reported magnetic mesoporous nanostructured catalyst. Firstly, the protection of alcohols was developed through their transformation to trimethylsilyl ethers. Then this reagent was applied for the acceleration of the acetylation of […]
In this study, the preparation of a new functionalized acidic metal-organic framework nanocatalyst formulated as Zr-MOF-N=CH-C6H4-SO3H has been reported. After characterization using different analysis methods such as FT-IR, XRD, SEM, EDX, TGA, and TEM, the average size of the nanoparticles was found to be between 42.5 and 50.4 nm in diameter. The Nanocatalyst was […]
A facile chemical mixing approach was used to prepare TiO2/ZnO photocatalystswith different mass ratios. The photodegradation activity was tested against paracetamol in an aqueous phase assisted by low UVC-light intensity (9 W). TiO2/ZnO particles mainly exhibited irregular shapes with uniform distributions and high crystallinity degree, the primary oxidation state in the structure is titanium […]
TiO2 is a highly desirable photocatalyst due to its abundance and low cost. However, its large band gap restricts its ability to absorb a significant portion of visible light. This issue can be addressed through cationic or anionic doping. In these instances, the impurity bands reduce the band gap. Nevertheless, in order to enhance […]
The sonocatalytic activity of the particles of the green Maghnite-H+ sonocatalyst was tested by the degradation of 2-Mercaptobenzothiazole (MBT) under ultrasonic irradiation was performed in an ultrasonic bath with a frequency of 40 kHz, and an ultrasonic power of 120 W for 120 min at room temperature followed by UV-visible analysis. This study was accompanied […]
Functionalized 2-amino-4H-chromenes have been successfully synthesized via cyclization of C-H activated acids, aromatic aldehydes, and active methylene compounds using a natural base catalyst derived from waste snail shells (Bellamya bengalensis) in the water at ambient temperature. Freshwater snail shells are significant biological materials with diverse uses. As an economical and environmentally benign alternative to […]
In this study, N1-N4-bis (3-(trimethoxysilyl)propyl)butane-1,4-diammonium trinitromethanide on titanium dioxide {TiO2-Bis[TMS-NH2+ C(NO2)3–]}an , was prepared and characterized by the use of different techniques including energy dispersive X-ray analysis (EDX), Fourier transform infrared spectroscopy (FT-IR), thermo gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM), and X-ray diffraction (XRD). In continue, the use of the prepared […]
Ag, Ce co-doped ZnO-polyaniline (Ag-Ce/ZnO-PANI) and Ag, Ce co-doped ZnO-reduced graphene oxide (Ag-Ce/ZnO-rGO) were synthesized via precipitation and in-situ polymerization, an environmentally friendly process. Structural and optical properties were characterized using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), transmission electron microscopy (TEM), diffuse reflectance spectra (DRS), N2 adsorption-desorption, photoluminescence spectra (PL), and […]
