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...

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?

(a) XRD pattern of the α-Al2O3 NPs obtained by removing the Fe matrix in the composites of α-Al2O3 NPs embedded in the Fe matrix through selective corrosion, showing a typical XRD pattern of α-Al2O3. (b) TEM image of the α- Al2O3 NPs obtained by removing the Fe matrix ...
After annealing, all samples revealed only hematite characteristics in XRD pattern and Raman spectra. Thickness of annealed thin films was similar to 350 nm measured via SEM cross-section image. The optical band gap and carrier concentration of samples were in the range of 2.13-2.16 eV and 6.28...
