Abstract

Ag3VO4 and Y2O3/Ag3VO4 photocatalysts were synthesized by precipitation and impregnation with the assistant of sodium dodecylbenzene sulfonate (SDBS), and V2O5, AgNO3 and Y(NO3)3×6H2O as raw materials, their structure and morphology characterized, and the synthesis mechanism was analyzed. The results showed that the absorption edge of Y2O3/Ag3VO4 was red-shifting, and the energy gap was 1.83 eV with SDBS assistance. The synthesized Y2O3/Ag3VO4 showed excellent photocatalytic activity and stability for degradation of rhodamine B (RhB) because of the adsorption enrichment of benzene and effective separation of photogenerated electron-hole pair. The degradation rate of 8 mg/L RhB in 200 mL solution was 94.2% by 0.08 g 3%Y2O3/Ag3VO4 in 15 min illumination.

Key words： Y2O3/Ag3VO4 photocatalyst; visible light; sodium dodecylbenzene sulfonate; degradation; rhodamine B; stability
