Hierarchically Structured Co3O4@Pt@MnO2 Nanowire Arrays for High-Performance Supercapacitors
Here we proposed a novel architectural design of a ternary MnO2-based electrode - a hierarchical Co3O4@Pt@MnO2 core-shell-shell structure, where the complemental features of the three key components (a well-defined Co3O4 nanowire array on the conductive Ti substrate, an ultrathin layer of small Pt nanoparticles, and a thin layer of MnO2 nanoflakes) are strategically combined into a single entit...

متن کاملMesoporous hexagonal Co3O4 for high performance lithium ion batteries
Mesoporous Co3O4 nanoplates were successfully prepared by the conversion of hexagonal β-Co(OH)2 nanoplates. TEM, HRTEM and N2 sorption analysis confirmed the facet crystal structure and inner mesoporous architecture. When applied as anode materials for lithium storage in lithium ion batteries, mesoporous Co3O4 nanocrystals delivered a high specific capacity. At 10 C current rate, as-prepared me...
متن کاملHierarchically ordered mesoporous Co3O4 materials for high performance Li-ion batteries
Highly ordered mesoporous Co3O4 materials have been prepared via a nanocasting route with three-dimensional KIT-6 and two-dimensional SBA-15 ordered mesoporous silicas as templates and Co(NO3)2 · 6H2O as precursor. Through changing the hydrothermal treating temperature of the silica template, ordered mesoporous Co3O4 materials with hierarchical structures have been developed. The larger pores a...
متن کاملSelf-stacked Co3O4 nanosheets for high-performance lithium ion batteries.
Self-stacked Co(3)O(4) nanosheets separated by carbon layers were synthesized via a facile method. They exhibit excellent electrochemical performance that results from superior electronic conductivity endowed by carbon, a reduced Li(+) diffusion length within the building blocks and a large electrode/electrolyte contact area due to the interspaces between the blocks.
