Abstract
A new electrosplay pyrolysis method where droplets are broken by a rectangular ac high voltage (named rectangular ac electrosplay pyrolysis method) is developed. The new method is compared with electrosplay pyrolysis methods using dc high voltage and using ac high voltage. X-ray diffraction patterns showed that particles synthesized from zinc nitrate and thiourea/distilled water solution and their/ethyl alcohol solution with the new method were ZnS. Deposition ratios and collection yield of the rectangular method were higher than the dc method but worse than the ac method. The mean diameters of particles formed by the rectangular method are respectively 194 nm and 41 nm when distilled water and ethanol were used as the solvent. These values were close to the mean diameter of particles formed by the dc method but much smaller than those by the ac method.
