Abstract

Mesoporous niobium nitride nanobelt arrays (Nb₄N₅NBAs) are fabricated directly on Nb foils by a hydrothermal reaction in KOH, protonation treatment in HNO₃, and calcination in an NH₃ambient. Themorphology, composition and pore structure of the Nb₄N₅NBAs are characterized in details. In addition,the mesoporous Nb₄N₅NBAs electrode has good specific capacitance (37.4 mF cm⁻², or 124 F g⁻¹) and delivers excellent rate performance due to the high porosity and good electron conductivity boding well for application to next-generation energy storage systems.
