Fabrication of MoO₂ Crystal/Carbon Nanofiber Composites via LiCl–KCl Flux

Abstract

Molybdenum dioxide (MoO 2 )/carbon nanofiber composites were successfully fabricated by LiCl-KCl flux cooling. The preparation was obtained by heating mixtures of MoO 3 , LiCl, KCl, and carbon nanofibers at 500 C for 10 h and then carrying out quenching in a furnace with the electric power turned off. The obtained MoO 2 /nanocarbon composites were blackish and had a metallic luster. The obtained composites have lengths of about 5 -150 mm and are in the form of prism. The carbon nanofibers and MoO 2 crystals were interfused densely with each other. Carbon nanofibers were found to act as a reducing agent.
