Synthesis and Characterization of Tungsten Micro-/Nanoparticles Using Tungstate-Based Inorganic-Organic Hybrid Nanobelts as Precursors

Abstract

Tungsten (W) micro-/nanoparticles were synthesized by thermally treating tungstate-based inorganic-organic hybrid nanobelts with a lamellar structure or the mixture of WO3 nanoplates and C6H12O6 in an Ar flow at 1000-1200 oC for 2-6 h. Phase compositions and morphologies of the W particles obtained were characterized by powder X-ray diffraction and scanning electron microscope.
