Abstract
Provided herein are methods for producing crystalline tungsten bronze oxide particles. The method may include atomizing a liquid solution comprising an alkali metal precursor and a tungsten precursor to produce droplets; mixing the droplets with one or more gaseous flows to produce a combined flow; flowing the combined flow through a heated reactor to provide crystalline tungsten bronze oxide particles having the formula MxWO3, wherein M is the alkali metal; and collecting the particles.
