The surface structure and high specific surface
area affect electrochemical response of partially oxidized
porous NiTi nanostructure in energy storage and corrosion
protection. NiTi nanostructure was synthesized by mechanical alloying of the elemental Ni and Ti powders with a high
energy ball milling at a stainless steel vial under an argon
atmosphere. Particularly, FTIR spectrum shows that a variety of the functional groups and Ni and Ti oxides on the
surface of the particles have been produced. X-ray diffractometer and transmission/scanning electron microscopy
techniques are used to investigate the microstructure of the
milled powder and electrochemical techniques are used to
evaluate electrochemical properties. The partially oxidized
NiTi alloy has capacitance of 60 F g− 1 in 6 M of KOH and
80 F g− 1 in 1 M Na2SO4 at different current densities, demonstrating the importance of NiTi in the charge transfer.
