摘　　要：分别采用浸渍法、水热合成法、均匀沉淀法和溶胶-凝胶法合成了TiO_(2)/ZSM-5复合材料,并采用XRD、SEM、EDS、FT-IR、UV-Vis和PL等表征手段对所制备的材料进行物相、形貌、结构和光学性能分析。室温下,以100 mL质量浓度为10 mg/L的罗丹明B(RhB)溶液为目标污染物,考察了不同材料对目标污染物的光催化降解率,并对光催化过程中主要活性物质进行分析。结果表明:浸渍法合成的复合材料光催化性能最好,降解率可达99.8%。不同活性组分中,超氧自由基(·O_(2))对RhB降解的影响最大。TiO_(2)/ZSM-5 composites were synthesized by impregnation,hydrothermal synthesis,homogeneous precipitation and sol-gel method,respectively. The phase,morphology,structure and optical properties of TiO_(2)/ZSM-5 were characterized by XRD,SEM,FT-IR,EDS,UV-Vis,and PL. At room temperature,with Rhodamine B(RhB)solution with 100 mL,10 mg/L as the target pollutant,the photocatalytic degradation rates of different materials were investigated and the main active substances in the photocatalytic process were analyzed. The results indicated that the composite material by impregnation method had the best degradation ratio,which can reach 99.8%. Among the different active components,superoxide radical(·O_(2))had the greatest effect on RhB degradation.
