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

Abstract

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 μm.

Ultra-long Na2V6O16·xH2O nanowires: large-scale synthesis and application in binder-free flexible cathodes for lithium ion batteries

“…[13][14][15] Zhou et al synthesized Na 0.33 V 2 O 5 $1.3H 2 O nanowires using hydrothermal method, based on the reaction of V 2 O 5 and Na 2 HPO 4 $12H 2 O. 16 Yu et al has successfully synthesized Na 2 V 6 O 16 $3H 2 O nanobelts using V 2 O 5 and NaF as raw materials by hydrothermal method without using any templates or catalysts. 17 In addition, Na 2 V 6 O 16 $xH 2 O nanowires have also been synthesized by a hydrothermal method using V 2 O 5 and NaOH.…”
