摘要

本研究将合成的Ag NPs/Ag3VO4/AgVO3/GO作为可见光敏感光催化剂，用于光催化降解水溶液中的直接红16染料(DR16)。采用XRD、FESEM、TEM、EDX和Dot图对合成的纳米复合材料进行了分析。研究了DR16染料浓度、AgNPs/Ag3VO4/AgVO3/GO投加量、时间和pH对光催化脱除DR16的影响。结果表明，pH、投加量和DR16浓度对光催化脱除染料的影响比时间更重要。结果表明:在DR16浓度为32 mg L的条件下，DR16的去除率为58.98%;Ag NPs/Ag3VO4/AgVO3/GO用量= 0.2 g 50 mL;pH = 4.5;结果表明，该纳米复合材料可作为一种高效的可见光催化剂，用于降解直红16染料。

Photocatalytic Degradation of Direct Red 16 Dye using Ag/Ag3VO4/AgVO3/GO Nanocomposite

In this research, synthesized Ag NPs/Ag3VO4/AgVO3/GO was applied as a visible-light sensitive photocatalyst for photocatalytic degradation of Direct Red 16 dye (DR16) from aqueous solutions. The synthesized nanocomposite was analyzed by XRD, FESEM, TEM, EDX and Dot mapping. The effect of DR16 dye concentration, AgNPs/Ag3VO4/AgVO3/GO dosage, time and pH on photocatalytic removal of DR 16 were studied. Results revealed that pH, dosage and DR16 concentration are more important parameters than time on photocatalytic removal of the dye. The results indicate that 58.98 % of DR16 removal was obtained under the following optimized conditions: DR16 concentration = 32 mg L; Ag NPs/Ag3VO4/AgVO3/GO dosage = 0.2 g 50 mL ; pH = 4.5; 300 W visible light for 155 min. So, it was concluded that the new nanocomposite can be used as an efficient visible-light photocatalyst for degradation of Direct Red 16 dye.
