The results showed the as‐prepared sample was α‐Fe2O3 phase with well‐crystallized rhombohedra structure. Scanning electron microscopy and transmission electron microscope showed that the synthesized α‐Fe2O3 product was consisted of nanospheres. The Brunauer–Emmett–Teller showed the synthesized...
The improved electrochemical performance of the composite can be attributed to the well-defined structure, high conductivity, and hierarchical porosity of OMPC as well as the unique α-Fe2O3 NPs with cube-like morphology well-anchored on the OMPC support, which makes the composite a promising ...
The morphology and interface structure of α-Fe2O3 islands grown on α-Al2O3 single crystals (sapphire) by Fe-ion-implantation and annealing in an oxidizing atmosphere have been studied using transmission electron microscopy. The α-Fe2O3 islands have the orientation relationship of [0001]α-...

Self-assembled α-Fe2O3 mesocrystals/graphene nanohybrids have been successfully synthesized and have a unique mesocrystal porous structure, a large specific surface area, and high conductivity. Mesocrystal structures have recently attracted unparalleled attention owing to their promising application in ...
Because of the unique porous structure, the potential application in water treatment of the α-Fe2O3 porous nanorods was investigated. The UV−vis measurements suggest that the a... 展开 关键词: hematite ionic liquid superstructures porous materials magnetic properties ...
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?
