Description
In situ hydrogenation of orthorhombic molybdenum trioxide (α-MoO
3
) nanowires has been achieved on a large scale by introducing alcohol during the hydrothermal synthesis for electrochemical energy storage supercapacitor devices. The hydrogenated molybdenum trioxide (H
x
MoO
3
) nanowires yield a specific capacitance of 168 F g

at 0.5 A g

and maintain 108 F g

at 10 A g

, which is 36-fold higher than the capacitance obtained from pristine MoO

nanowires at the same conditions. The electrochemical devices made with H

MoO

nanowires exhibit excellent cycling stability by retaining 97% of their capacitance after 3000 cycles due to an enhanced electronic conductivity and increased density of hydroxyl groups on the surface of the MoO
