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 […]
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 […]
Michael addition of pyrimidine and purine nucleobases to substituted as well as unsubstituted α,β-unsaturated esters efficiently proceeds in the presence of catalytic amount of zinc oxide in ionic liquid 1-butyl-3-methylimidazolium bromide (ZnO/[bmim]Br) under microwave irradiation to afford carboacyclic nucleosides, as biologically important compounds, in good to excellent yields and in short reaction times.
