Hydrothermal Synthesis of a Novel Sodium Vanadium Bronze with Single-crystalline Nanobelt-like Morphology

A novel sodium vanadium bronze was successfully synthesized at 180 °C by a facile hydrothermal method. XRD, SEM, TEM, and XPS techniques were used to characterize the synthesized bronze. SEM and TEM analyses reveal that the bronze exhibits nanoblet-like morphology with an average width of ca. 55 nm and lengths from several to tens (mu)m.
