Abstract: Hydrous manganese dioxide nanostructures were synthesized via a catalytic oxidation reaction mechanism at mild temperatures. It was found that the morphology of the manganese dioxide nanostructures was significantly influenced by the pH of the reaction system. With increasing pH the morphology of manganese dioxide nanostructures changed from urchin-like structures to nanobelts. The capacitive performance was investigated by using cycle voltammetry and galvanostatic charge/discharge techniques. Hydrous manganese dioxide nanostructures obtained from a basic solution exhibited a capacitance of 262 F g − 1 at a current density of 250 mA g − 1 and a capacitive retention of 75% after 1200 cycles, suggesting that this is a promising electrode material for supercapacitors. The high specific capacitance is attributed to the hydrous nature coupled with a high surface area (181 m 2 g − 1 ) of the manganese dioxide nanostructure.

Abstract: We report the synthesis of Fe3O4@C core-shell nanoparticles (FCNPs) by using a facile one-step solvothermal method. The FCNPs consisted of Fe3O4 particles as the cores and amorphous uniform carbon shells. The content of Fe3O4 is up to 81.6 wt%. These core-shell nanoparticles are aggregated by primary nanocrystals with a size of 10-12 nm. The FCNPs possess a hollow interior, high magnetization, excellent absorption properties and abundant surface hydroxyl groups. A possible growth mechanism of the FCNPs is proposed. The role of glucose in regulating the grain size and morphology of the particles is discussed. The absorption properties of the FCNPs towards Cr(VI) in aqueous solution is investigated. We demonstrate that the FCNPs can effectively remove more than 90 wt% of Cr(VI) from aqueous solution.
