Semiconductor particles for water splitting photocatalyst, photocatalyst formed by semiconductor particles, and synthesis method thereof

Abstract

The present invention relates to semiconductor particles for water decomposition photocatalysts, photocatalysts formed by semiconductor particles, and synthesis methods thereof. The semiconductor particles are used as photocatalysts by adding a co-catalyst, the photocatalysts are used for water decomposition reactions in which water molecules are decomposed into oxygen molecules and hydrogen molecules by light irradiation, and the semiconductor particles contain strontium titanate doped with scandium. A synthesis method for semiconductor particles for the photocatalyst comprises the following synthesis steps: mixing strontium chloride (SrCl 2 ), SrTiO 3 ) and scandium oxide (Sc 2 O 3 ) obtain a mixture and sinter the mixture to synthesize the semiconductor particles containing strontium titanate doped with scandium.
