In this study, the synthesis of nitrogen-doped zinc oxide nanoparticles with a cabbage like morphology (N-ZnONCBs) by hydrothermal method using acetate dihydrate as precursor and hydrazine monohydrate nitrogen source is reported. N-ZnONCB were characterized UV-visible Spectroscopy (UV-Vis), Fluorescence Spectroscopy, Fourier Transmittance Infrared (FTIR), X-ray diffraction (XRD), Raman Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Transmission (TEM), Dispersive (EDS)...
Polyaniline (PANI)-wrapped TiO2 nanorods (PANI/TiO2), obtained through the oxidative polymerization of aniline at surface hydrothermally presynthesized nanorods, were evaluated as photocatalysts for degradation Bisphenol A (BPA). Fourier-transform infrared spectroscopy analysis revealed successful incorporation PANI into by appearance peaks 1577 and 1502 cm-1 that are due to C=C C-N stretch benzenoid or quinoid ring in PANI. Brunauer-Emmett-Teller PANI/TiO2 had almost double area (44.8999...
Heavy metal ions are toxic causing a variety of health complications. mainly include Cr(VI), Hg(II), Pb(II), Cd(II), Cu(II), Fe(III) and Co(II). The adsorption technique is the most practical in removing from water since it cost effective, simple to operate has high removal efficiency. After heavy metals spent adsorbent need be disposed. approach focus on laden adsorbents because these present greater challenge towards potential secondary pollution contaminants cannot degraded. If improperly...
