摘      要：Ternary direct dual Z-scheme Bi_(3)T_(a)O_(7)/Bi_(2)S_(3)/SnS_(2) photocatalyst was successfully prepared by hydrothermal *** composite photocatalysts exhibited high photocatalytic performance on both Cr(Ⅵ)reduction and tetracycline(TC)degradation under the irradiation of visible *** results manifested that the photogenerated charge transfer efficiency was improved after forming the dual Z-scheme *** a result,the composite catalysts exhibited higher photocat-alytic degradation efficiency than the corresponding single *** apparent rate constant(k)value of the best sample BBS-3 for TC degradation was 0.0403 min^(-1),which was 40 times,8 times,and 18 times higher than that of single *** the k value of BBS-3 for the Cr(Ⅵ)reduction was 0.0249 min^(-1),it was about 23 times,7 times,and 18 times that of single *** experiments indicated that the BBS-3 had good photocat-alytic ***,the possible mechanism on Cr(Ⅵ)reduction and TC degradation was proposed based on the experimental results.
