In the present study, the effects of calcium doping on the performance of the co-precipitated Cu-MgO catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. The results proved that the addition of this promoter had a remarkable impact on the catalytic performance. The conversion of furfuraldehyde enhanced up to 83% […]
Ni catalysts supported on Nano porous catalysts were prepared by the impregnation method and tested for vapor phase hydrogenation of benzene. The textural and physico-chemical properties of Ni catalysts were characterized by the X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope and N2 adsorption-desorption analysis. The catalytic evaluation revealed that the best selectivity to benzene […]
This study was performed with the aim of investigating the efficiency of the Nano photocatalytic of ultraviolet and titanium dioxide compound and rice husk silica adsorbent (UV/TiO2/RHS) in removal reactive red 198 dye from synthetic aqueous solutions. The removal of reactive red 198 dye was done in batch reactors with a volume of 250 ml […]
A heterogeneous catalyst containing manganese Schiff base complex (derived from 2,4-dihydroxybenzadehyde and 1,2-phenylenediamine) is produced by covalent anchoring in MCM-41 matrix. The synthesized catalyst was characterized by X-ray diffraction pattern (XRD), inductivity coupled plasma (ICP), Fourier transform infrared (FT-IR) spectroscopy, N2 sorbtion-desorbtion isotherm and by transmission electron microscopy (TEM). The obtained catalyst was used in […]
Stereoelectronic effects is a bridge between structure and reactivity [1]. Anomeric effect plays an important role in the domain of stereoelectronic interaction and can be used for description of several unusual phenomena. Intramolecular negative hyperconjugation is also known as anomeric effect [2]. In anomeric effect, both donor (lone pairs) and acceptor groups (electronegative elements) coexist […]

This work describes the simplest method of synthesis of a carbonized cobalt catalyst based on an available natural mineral, clay activated with nitric acid, which showed high selectivity and activity in hydrogenation of acetylene to ethylene. Metal catalysts with cobalt contents of 5 %-7 % in a bentonite clay carrier from the Tonkeris deposit were […]
The goal of this research is to create nanostructured metal free phosphorous doped Boron nitride (P-BN) and phosphorous-carbon co-doped Boron nitride (CP-BN) that serve as photocatalysts when exposed to UV light. P-NPs were well diffused in aqueous solution. The nanostructured materials were characterized using XRD, SEM-EDX, and UV-Vis spectrophotometry. Based on the characterization results, phosphorous […]
