Highly crystallized cubic NixCo3xO4 with porous hierarchical structures was synthesized through a simple coprecipitation method followed by calcination at temperatures above 400掳C in air. The performances of the samples as anode materials for Na-ion batteries were evaluated. At 100mAg1 in the 50th...
Direct assembling 2D zeolitic imidazolate frameworks-derived (ZIFs)-derived Ni-Co oxide on Ni foam (NixCo3−xO4/Ni foam) is a very attractive way to obtain high performance for electrochemical energy storage device. In this work, the highly optimized NixCo3−xO4/Ni foam was prepared via...
High-quality nickel cobaltite (NixCo3xO4, 0 ≤ x ≤ 1) nanopowders with various nickel contents have been prepared by a facile hydrothermal method, calcined in air at 300°C for 2 h, then coated on the surface of indium tin oxide sheets by electrophoretic deposition. The optical, ...
Herein, NixCo3-xO4 nanoneedle arrays grown on 3D porous nickel foam (NF) was synthesized as a bifunctional electrocatalyst with OER and HER activity for full water splitting. Benefiting from the advantageous structure, the composite exhibits superior OER activity with an overpotential of 320 mV ...
