✦ Synopsis

Molybdenum disulfide made by ultrasonic spray pyrolysis

Workers at the University of Illinois in Urbana-Champagne have made molybdenum disulfide catalyst particles by a new process which improves their catalytic activity. Droplets of aqueous ammonium tetrathiomolybdate and colloidal silica are sprayed into a furnace, The product is leached with hydrofluoric acid which removes the silica, leaving particles of highly active molybdenum disulfide.
