1,5-benzodiazepines are regarded as one of the most important classes of heterocyclic compounds as privileged structures and have vast range of applications in the field of medicine and chemistry. They are therefore attractive synthetic targets for organic and medicinal chemist. The current review article mainly covers the multicomponent green chemistry approaches for the synthesis of […]
The current study examined the effect of metal oxide catalysts on the sorption and photocatalytic efficiencies for the removal of ciprofloxacin and ofloxacin in water. ZnO and TiO2 catalysts are prepared using a suitable method based on the sol-gel process, which have a great change in structural and textural properties. The structure and surface area […]
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 […]
SO4/ZrO2 heterogeneous acid catalyst was prepared by wet impregnation method from ZrO2 precursor involved variations in H2SO4 concentration (0.5; 1.0; 1.5 M) and calcination temperature (400, 500, 600 ℃) to yield catalyst with the highest acidity value. The catalysts produced were characterized using Fourier Transform Infrared (FTIR) spectrometer, X-Ray Diffractometer (XRD), Scanning Electron Microscope-Energy Dispersive […]
