The chemical composition, morphology and surface properties of photocatalytic ternary heterojunction were characterized by XRD, UV-Vis, FE-SEM, TEM, EDS, XPS techniques and BET analysis. The PL emission, transient photocurrent and EIS Nyquist plot were investigated for separation and migration of ...
The XRD pattern of hematite α-Fe2O3 nanoparticles were indexed to rhombohedral structure of α-Fe2O3, while the TEM images illustrate the flaky structure of graphene supported by hematite nanoparticles. The rGO/\\(\\alpha\\)-Fe2O3 nanocomposites showed enhanced photocurrent of ~?4?mA cm?
In the present work flower-like, alpha-Fe2O3 were synthesized by ethylene-glycol mediated polyol method. The synthesized flower-like, alpha-Fe2O3 were separated cadmium (Cd2+) chromium (Cr6+) and lead ions (Pb2+) from wastewater. XRD pattern and FESEM images show the obtained sample is...
Phosphorous-doped Ti-Fe mixed oxide (P-TiO2-alpha Fe2O3) catalysts were prepared by the microwave-assisted sol-gel route and characterized using XRD, SEM, N-2 physisorption, UV-vis diffuse reflectance, FTIR, and XPS. P-TiO2-alpha Fe2O3 was evaluated during the degradation of a sulfonamide...
The size of nanoparticles was determined to be 42 nm evaluated by XRD patterns using the Scherrer equation. This method allowed the formation of pure hematite nanoparticles with good and stable crystallographic characteristics. This procedure can be an effective method for synthesizing hematite ...
XRD, SEM, TEM and EDS analyses indicated that their diameters and lengths were similar to 40 nm and 0.35-1.2 mu m, respectively, in which the largest thickness of ZnO shells was about 10 nm. The heteronanostructures exhibited a dramatic improvement in ethanol sensing characteristics compared to...
