摘要：The Ag/h-BN/Bi2O3 ternary composite was facilely fabricated via self-assembly combined with in situ reduction. Characterization results showed that the as-prepared Ag/h-BN/Bi2O3 possessed distinct surface plasma resonance (SPR) and Mott-Schottky heterostructure, resulting in significant enhancement of catalytic activity for RhB removal, the reaction rate constant (2.26x 10 (2) min 1) is 2.5 times that of h-BN/Bi2O3 under visible-light irradiation for 2 hours, which was mainly ascribed to the SPR and Mott-Schottky heterostructure result in Ag/h-BN/Bi2O3 enhanced visible-light harvesting capacity and the effectual spatial separation of photoinduced carriers. The quenching process of reactive species indicated that h(+) and *O-2 play dominant role in the degradation for pollutants. This work demonstrates that Ag/h-BN/Bi2O3 is a promising stability photocatalyst for water purification.
