The iron particles extracted from biological and abiotic reactors were used to be characterized and compared with each other. TEM, SEM, XRD and XPS were utilized to observe and quantify the particle morphology and oxidized iron precipitates. Unlike the Fe3O4 and Fe2O3 coating of nanoscale zero-valent iron (NZVI) particles in the abiotic reactors, the major component of the coating of the activated...
Gamma-alumina (γ-Al2O3) nanofibres with 30˜1500 nm diameter have been prepared by calcination of anhydrous aluminium chloride/polyvinylpyrrolidone (AlCl3/PVP) hybrid fibres about 5 h at 900°C which were prepared by electrospinning as precursor. Nano palladium (Pd) particles were deposited by electroless plating deposition (EPD) onto γ-Al2O3 nanofibre surfaces to form Pd/γ-Al2O3 nanofibre (PANF) catalyst...
In this letter, zinc oxide (ZnO) nanophosphors have been fabricated in oxygen/nitrogen plasma circumstance by Zn or ZnO targets using pulsed Nd:YAG laser ablation. Cathodoluminescence (CL) technique with energy-controlled electron beams, combined with X-ray diffraction (XRD) and X-ray photoemission spectroscopy (XPS) analyses, was used to study the structure of nano-sized ZnO particles fabricated...
In the present study, non-stoichiometric tungsten oxide (WO3-x) nanomaterials synthesized by a modified plasma arc gas condensation technique were added into anatase titanium oxide (a-TiO2) which was used as photoanode materials in dye-sensitized solar cells (DSSC). The WO3-x/a-TiO2 sample was characterized by FESEM, XRD, HRTEM, XPS and UV-visible spectra techniques. The photovoltaic efficiency of...
