Template-free formation of uniform urchin-like α-FeOOH hollow spheres with superior capability for water treatment
Uniform urchin-like α-FeOOH hollow spheres assembled from nanoneedles have been synthesized via a facile and green one-pot method. By simply adjusting the amount of glycerol in the reaction system, hierarchical urchin-like ...
One-pot synthesis of ultra-light nickel nanofoams composed of nanowires and their transformation into various functional nanofoams
Ultra-light Ni nanofoams composed of nanowires have been synthesized on a large scale by a facile reflux approach. From the Ni nanofoam, many other functional nanofoams, composed of semi-hollow NiO nanowires, multi-generation ...
Porous Co3O4 nanowires derived from long Co(CO3)0.5(OH)·0.11H2O nanowires with improved supercapacitive properties
Porous Co3O4 nanowires with large aspect ratio have been obtained by annealing long Co(CO3)0.5(OH)·0.11H2O precursor nanowires synthesized by a facile hydrothermal method. The results show that the amount of the additive ...
Formation of 1D hierarchical structures composed of Ni3S2 nanosheets on CNTs backbone for supercapacitors and photocatalytic H2 production
One-dimensional (1D) hierarchical structures composed of Ni3S2 nanosheets grown on carbon nanotube (CNT) backbone (denoted as CNT@Ni3S2) are fabricated by a rational multi-step transformation route. The first step involves ...
Unusual formation of single-crystal manganese sulfide microboxes co-mediated by the cubic crystal structure and shape
Kept cubic: MnS microboxes, which act as an anode material for lithium ion batteries, are synthesized by a simple H2S gas sulfidation approach (TEM images show porous and hollow microcubes and a microbox). The formation ...
Embedding sulfur in MOF-derived microporous carbon polyhedrons for lithium-sulfur batteries
Microporous carbon polyhedrons (MPCPs) are derived from unique MOF polyhedrons, and used as a model microporous carbon host for sulfur in Li–S batteries. Systematic investigations have been carried out to reveal the effects ...
