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...
Two-dimensional (2D) materials with structures having diverse features are promising for application in energy conversion and storage. A stronger layered orientation can guarantee fast charge transfer along the 2D planes...
