Rational construction of self-supporting electrode has been extensively investigated in energy conversion and storage. Herein, hierarchical N-doped carbon encapsulated Ni3S2 grown on 3D porous Ni foam (H-Ni3S2@NC/NF) is controllably synthesized...
The development of energy conversion and storage devices and the disposal of solid waste represent two major challenges for environmental sustainability.
Oxygen reduction (ORR), oxygen evolution (OER), and hydrogen evolution (HER) reactions are extremely important electrochemical reactions for electrochemical energy conversion and storage.
A single step redox approach that transformed the crystalline Ni-MOF to amorphous nickel boride (NiB) nanostructures showed excellent electrocatalytic (oxygen evolution reaction; OER) and charge storage (supercapacitor) performances.
