  • Semiconductor photocatalyst and preparation method thereof
    Patent number: 11084028
    Abstract: The present invention discloses a novel magnetic BiOCl—Bi24O31Cl10/MnFe2O4—Fe2O3 semiconductor photocatalyst as a staggered multi-heterojunction nano-photocatalyst for pharmaceutical effluents remediation, and preparation method and use thereof. The semiconductor photocatalysts are at weighted ratios 9:1 4:1, 7:3 and 3:2 of BiOCl—Bi24O31Cl10 and MnFe2O4—Fe2O3 semiconductor. The BiOCl—Bi24O31Cl10/MnFe2O4—Fe2O3 semiconductor photocatalyst with 10% MnFe2O4—Fe2O3 is a solar light activated photocatalyst for pharmaceutical effluents remediation. The pharmaceutical effluents include ofloxacin antibiotic.
