Abstract

A new electrospray pyrolysis method (named ac electrospray pyrolysis) is developed where droplets with a diameter smaller than 0.3 μm are formed through the breakdown of droplets by an ac voltage. The effectiveness of electrospray pyrolysis is demonstrated through the ZnS particle synthesis from the zinc nitrate and thiourea/ethyl alcohol solution. The amount of particles generated by the ac electrospray pyrolysis were about 10 times that by the conventional dc electrospray method at a given condition (the gas flow rate : 2 L/min, the furnace temperature : 873 K, the feeding rate of solution : 45 ∼ 38.5 mL/h) . SEM photographs showed that the particles prepared by ac voltage were agglomerated and the average size of the primary particles was almost the same as that of particles produced with dc voltage. X-ray diffraction patterns showed that particles produced by ac electrospray were ZnS.
