Template-free synthesis of hierarchical hollow V2O5 microspheres with highly stable lithium storage capacity

Additive-free synthesis of 3D porous V2O5 hierarchical microspheres with enhanced lithium storage properties

A facile synthesis of novel 3D porous V2O5 hierarchical microspheres has been developed, based on an additive-free solvothermal method and subsequent calcination. Due to their unique structure, these V2O5 microspheres display a very stable capacity retention of 130 mA h g (1) over 100 cycles at a current rate of 0.5 C, and show excellent rate capability with a capacity of 105 mA h g (1) even at...

Template-Free Fabrication of Bi2WO6 Hierarchical Hollow Microspheres with Visible-Light-Driven Photocatalytic Activity

Highly hierarchical hollow bismuth tungstate (Bi2WO6) microspheres self-assembled by thin nanoplates have been fabricated via a facile template-free solvothermal route. The possible growth pattern and formation mechanism of hierarchical hollow Bi2WO6 microspheres was investigated. The excellent visible-light-driven photocatalytic performance on rhodamine B (RhB) degradation was displayed by hie...

Bifunctional highly fluorescent hollow porous microspheres made of BaMoO 4 : Pr 3 + nanocrystals via a template - free synthesis †

nanocrystals by a facile template-free synthesis. All the as-synthesized hollow microspheres are welldispersed with a diameter of 2–4 mm and the BaMoO4 : Pr 3+ nanocrystals measure 30–60 nm in diameter. It is observed that there are a large amount of pores with an average diameter is 17.5 nm in the shell of these BaMoO4 : Pr 3+ hollow microspheres, thereby exhibiting a great promise for drug de...

High-areal-capacity lithium storage of the Kirkendall effect-driven hollow hierarchical NiS(x) nanoarchitecture.

Three-dimensional (3-D) architectures can provide significant advantages as lithium ion microbattery electrodes by lengthening the vertical dimension. In addition, the nanoscale hierarchy and hollow properties are important factors for enhancing the performance. Here, we prepared a 3-D nickel sulfide nanoarchitecture via a facile low-temperature solution route. A Kirkendall effect-driven sulfid...
