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 […]
Nb2O5 nanoparticles were synthesized by the hydrothermal method. Structural, morphological and elemental analysis of synthesized Nb2O5 nanoparticles was carried out using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy, respectively. The average crystal size calculations were performed on the basis of X-ray diffraction pattern and were about 12.44 nm. The synthesized […]
Metal-organic framework 5 (MOF-5) and bimetallic MOF-5s (Co/Zn and Ni/Zn) were prepared via a simple solvothermal method. Samples were characterized by various techniques such as powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), UV-Vis diffuse reflectance spectroscopy (DRS), inductively coupled plasma (ICP) and elemental analysis (EA). Photocatalytic decolorization of methylene blue […]
Porous ZnO-hydroxyapatite nanocomposite was prepared by dissolution of a rock phosphate ore in an acidic medium followed by alkaline precipitation. Its photocatalytic activity was assessed for the degradation of paracetamol as one of the most commonly prescribed pharmaceutical drugs and methylene blue as dye model. Thanks to its good porosity, the 40ZnHAp nanocomposite adsorbed the […]
The 4-nitrophenol (4-NP) and methylene blue (MB) are commonly used in many industries and remain in the industrial effluent. They have an adverse effect on the environment if not treated properly. Therefore, it is essential to develop a convenient method to remove such toxic chemicals from wastewater. Here, Ag/Ag2O nanoparticles (NPs) were prepared from AgNO3 […]
A series of bismuth-silicate photocatalysts were synthesized via the sol-gel method for photodegradation of methylene blue (MB) under sunlight irradiation, utilizing rice husk ash as a silica precursor. The scanning electron microscopy/energy dispersive X-ray (SEM/EDX) analysis detected Bi content in 3-10 wt% range. Furthermore, it can be seen that the porosity decreased as the Bi […]
