Three-dimensional (3D) nanostructures of α-Fe2O3 materials, including both hollow sphere-shaped and yolk-shell (core-shell)-shaped, have been successfully synthesized via an environmentally friendly hydrothermal approach. By expertly adjusting the reaction time, solid, hollow, shaped can be selectively synthesized. Yolk-shell nanospheres display outer diameters 350 nm, interstitial spaces layer is intimately sandwiched between inner shell nanostructures. The possible growth mechanism...
The unique properties of two dimensional (2D) materials make them promising candidates for chemical and biological sensing applications. However, most 2D nanomaterial sensors suffer very long recovery time due to slow molecular desorption at room temperature.
