Tungsten nanoparticles from liquid-ammonia-based synthesis†
Abstract
Tungsten nanoparticles were obtained from liquid-ammonia-based synthesis via reduction of WCl6 with dissolved sodium. The W0 nanoparticles exhibit a diameter of 1–2 nm and can be dispersed in alkanes, showing a grayish-orange color due to red-shifted plasmon resonance absorption.
