Unsupported molybdenum (Mo) micro/nanoparticle size range catalysts have been synthesized via precursor salts dissolved within a water-in-oil emulsion and online injected to a decomposition zone simulating processing conditions. The particles were characterized via DLS, reactivity tests and SEM. The effect of decomposition temperature on particle sizes was studied in both a horizontal reactor and vertical reactor configuration.
