C,N-LiFePO4 mesocrystals were successfully prepared through topotactic conversion of ferric giniite using an ionic liquid as a carbon and nitrogen source, which provided a pathway for rapid electron transfer and shortened the Li+ diffusion distances. Thus, good cycling stability and rate capability are achieved, showing improvement using the strategy of mesocrystalline electrodes coated with N-doped carbon from an ionic liquid.

Novel α-Ag3VO4 nanostructures have been successfully synthesized via a facile and repeatable precipitation method by using n-BA as precipitant and complexing agent. Photocatalytic property tests for decomposition of RhB demonstrate that the as-prepared nanostructures have enhanced photocatalytic activity. [ABSTRACT FROM AUTHOR]

The steep rhombohedra MnCO3microcrystals and their large-scale assembly into regular elongated patterns are obtained viaa novel surfactant-free route by adjusting the proportion of the mixed solvent (methanol and DMF). We hope this synthetic strategy can provide a new approach to synthesize metal carbonates. [ABSTRACT FROM AUTHOR]

Ammonium phosphate ((NH4)3PO4) has been first used as a surface treatment reagent for Li-rich cathode materials. Compared to the conventional surface treatment, the samples treated with (NH4)3PO4 exhibit an ultra-high initial Coulomb efficiency of 98.0% and excellent cycling stability. This is mainly attributed to the simultaneous construction of surface integrated structures, including oxygen vacancies, spinel phases, and Li3PO4 coating. This study demonstrates the effectiveness of ammonium phosphate surface treatment and provides a new idea for designing other cathode materials. [ABSTRACT FROM AUTHOR]

The Bi2S3nanomaterials with various morphologies such as nanorods, nanowires, nanowire bundles, urchin-like microspheres and urchin-like microspheres with cavities have been successfully synthesized through a simple hydrothermal method. Experimental results indicate that sulfur sources play crucial roles in determining the morphologies of Bi2S3products. Moreover, formation mechanisms of different Bi2S3nanostructures are discussed based on understanding of the growth habit of Bi2S3crystal. Finally, we also studied the morphologies-dependent electrochemical and optical properties of the as-synthesized Bi2S3nanomaterials. [ABSTRACT FROM AUTHOR]

Morphology control of bismuth sulfide (Bi2S3) nanostructures, from one-dimensional nanorods with various aspect ratios, to various kinds of two-dimensional nanofabrics (dense nanofabrics and spark nanofabrics) to three-dimensional urchin-like microspheres and crossed nanofabrics, has been achieved viaan ionic liquids-assisted hydrothermal route, by adjusting the active state of the BiOCl, the characteristics and concentration of the ionic liquid used and the reaction temperature. Reasonable growth mechanisms for the Bi2S3with different morphologies are proposed, based on active state of the intermediate BiOCl, characteristics of the ionic liquids used and the crystal growth habits of Bi2S3. More importantly, we introduce the concept of two different states of the intermediate BiOCl (active BiOCl and inert BiOCl) to explain the growth mechanisms of nanofabrics, nanorods and urchin-like microspheres, from different crystal growth processes. Moreover, electrochemical measurements demonstrate that Bi2S3nanofabrics and urchin-like microspheres possess higher initial Li intercalation capacity than graphitic materials (372 mA h g−1), and their cyclic performances are highly dependent on their morphologies.

Ferrimagnetic Fe3S4nanowalls and triple hierarchical microspheres have been fabricated viaan ionic liquid-modulated solution–phase process, respectively. Magnetic hysteresis measurements demonstrate that their morphology–dependent magnetic properties might be originated from their unique nanostructures. [ABSTRACT FROM AUTHOR]
