摘要
以硫酸钛为原料,采用共沉淀法,制备了一系列纳米二氧化钛复合石墨烯催化剂,采用XRD和FTIR对样品进行表征。通过紫外光照射亚甲基蓝溶液光催化降解实验,研究石墨烯的加入量对TiO2光催化性能的影响,结果表明,TiO2-GO-5具有最佳的光催化性能。在pH=6.00、TiO2-GO-5的投加量为0.070 g/50 mL、光照3 h条件下,100 mg/L亚甲基蓝溶液的脱色率达到最大值为90.52%。
A series of nano TiO2-GO was synthesized using Ti( SO4)2 by coprecipitation method. The synthesized samples were characterized by XRD and FTIR. The catalytic activities were evaluated by degradation of methylene blue solution under uv light. The results showed that TiO2-GO-5 had the best photocatalytic properties.The dosage of TiO2-GO-5 was 0. 070 g /50 mL wastewater; irradation time was 3 h,and the decolorization rate of100 mg /L methylene blue solution reached a maximum of 90. 52% at pH value of 6. 00.
