The comparative lithium storage properties of urchin-like hematite spheres : hollow vs. solid
Urchin-like α-Fe2O3 spheres, hollow or solid, are obtained by thermally annealing their α-FeOOH precursor structures, which are synthesized via a facile hydrothermal method. The “hollowness” of these α-FeOOH spheres can ...
Green synthesis of NiO nanobelts with exceptional pseudo-capacitive properties
NiO nanobelts are prepared by a simple, green method. The as-prepared NiO nanobelts have supercapacitive performance that is superior to other NiO-based electrode materials, with a very high specific capacitance of ≈600 F ...
Sandwich-structured TiO2-Pt-graphene ternary hybrid electrocatalysts with high efficiency and stability
The practical application of low temperature fuel cells is largely hindered by the unavailability of efficient electrocatalysts with high activity and stability. A promising strategy to design highly active electrocatalysts ...
