Atomic-layer-deposition-assisted formation of carbon nanoflakes on metal oxides and energy storage application
Nanostructured carbon is widely used in energy storage devices (e.g., Li-ion and Li-air batteries and supercapacitors). A new method is developed for the generation of carbon nanoflakes on various metal oxide nanostructures ...
Black phosphorus quantum dots
As a unique two-dimensional nanomaterial, layered black phosphorus (BP) nanosheets have shown promising applications in electronics. Although mechanical exfoliation was successfully used to prepare BP nanosheets, it is ...
Multifunctional architectures constructing of PANI nanoneedle arrays on MoS2 thin nanosheets for high-energy supercapacitors
Multifunctional MoS2@PANI (polyaniline) pseudo-supercapacitor electrodes consisting of MoS2 thin nanosheets and PANI nanoarrays are fabricated via a large-scale approach. The superior capacitance retention is retained up ...
Graphene quantum dots coated VO2 arrays for highly durable electrodes for Li and Na Ion batteries
Nanoscale surface engineering is playing important role in enhancing the performance of battery electrode. VO2 is one of high-capacity but less-stable materials and has been used mostly in the form of powders for Li-ion ...
Facile synthesis of metal oxide/reduced graphene oxide hybrids with high lithium storage capacity and stable cyclability
We report an environment-friendly approach to synthesize transition metal oxide nanoparticles (NPs)/ reduced graphene oxide (rGO) sheets hybrids by combining the reduction of graphene oxide (GO) with the growth of ...
Enhanced Lithium Storage Performance of CuO Nanowires by Coating of Graphene Quantum Dots
Graphene quantum dots prove useful in lithium-ion batteries. This work introduces graphene quantum dots for the first time as surface coating material for lithium-ion battery electrodes, exemplified by copper oxide nanowires. ...
