摘要：
Porous NiO nanowall arrays (NWAs) grown on flexible FeCoNi alloy have been successfully synthesized by using nullaginite (Ni2(OH) 2CO3) as precursor and investigated as supercapacitor electrodes. In details, we adopted a simple hydrothermal method to realize Ni2(OH)2CO3 NWAs and examined their robust mechanical adhesion to substrate via a long-time ultrasonication test. Porous NiO NWAs were then obtained by a post-calcination towards precursors at 500 °C in nitrogen atmosphere. Electrochemical properties of as-synthesized NiO NWAs were evaluated by cyclic voltammetry and galvanostatic char...
