Controllable nanoarchitecture arrays of the transition metal selenide, supported on conductive substrates, are promising materials for high-performance electrochemical energy storage and conversion applications. Herein, Ni3Se2 nanowire arrays with a rich-grain-boundary are rationally grown on a nickel foam (

Can ni 3 SE 2 nanosheets be used as attracting electrode materials?

In summary, we have triumphantly used a facile two-step strategy to Ni 3 Se 2 nanosheets on the surface of the 3D NiSe nanowires arrays directly deposited on Ni foam as attracting electrode materials for high-energy ASC device.

What is the electrochemical double layer capacitance of NISE nwas@ni3 SE 2 NSS?

The calculated results (Fig. 6(d)) show that the electrochemical double layer capacitance of the NiSe NWAs@Ni3 Se 2 NSs/NF is 3.25 mF cm −2, which is higher than NiSe NWAs/NF (2.82 mF cm −2) and Ni 3 Se 2 NSs/NF (2.67 mF cm −2). It reveals the composite electrode possesses more active reaction sites.

What is a Ni 3 SE 2 electrode used for?

When used as a two-dimensional (2D) electrode for water splitting reaction, the Ni 3 Se 2 electrode exhibits high catalytic activity to achieve 100 mA cm −2 at an overpotential of 320 mV in the oxygen evolution reaction and a low overpotential of 95 mV at a current density of 50 mA cm −2 in the hydrogen evolution reaction in a 1.0 M KOH solution.
