| Popis: | In this study, a novel (NH4)3PW11O39Sn/TiO2 composite was successfully obtained by dipping method. The products were evaluated by XRD, SEM, XPS and DRS. The results showed that the (NH4)3PW11O39Sn/TiO2 had a good visible-light response and the Acid Red 3R degradation rate could reach 100% under visible-light conditions after 30 min. Further scavenging experimental results revealed that the hole and OH both played a crucial role and the O2 played a minimal influence in the photocatalytic process. |
