Abstract |
The effect of the amorphous structure of metal oxide on its electrochemical functionalities is investigated with amorphous MoO2 and well-crystallized MoO2. Amorphous MoO2 nanoparticles are synthesized by soft-chemical redox reactions using KBH4 at room temperature. The amorphous MoO2 nanoparticles show better electrocatalytic hydrogen evolution reaction (HER) activity and sodium-ion battery (NIB) performance than does the well-crystallized MoO2 material, which is attributable to the greater surface area, higher electrochemical stability and better charge transfer kinetics of the amorphous MoO2 material. The present study highlights the beneficial effect of amorphous nature for optimizing the electrocatalyst/electrode performance of metal oxide. |
