Photocatalytic ActiVity of TiO2-HZSM-5 Composite for C.l.Reactive Red 2 Degradation

摘要：

A composite Of TiO2 and HZSM-5 zeolite was used for photocatalytic degradation Of C.I． Reactive Red 2(RR2)．With TiO2 concentration of 320 mg/l，the optimum composite was composed of TiO2 and HZSM一5 by the weight ratio of 1:10．The composite showed higher activity than the P25 powder in calcination temperature range from 400 to 600°C and 450°C can be the optimum calcination temperature．When irradiation time was 40 min，the composite degraded 96.8％of the initial RR2.94.9％of the dye was degraded in 70 min using pure TiO2．The RR2 degradation rate increased constantly with increasing composite photocatalyst concentration up to 320 mg/l．The activity of the composite grinded without ethanol was less than that of the composite photocatalyst grinded with ethanol．
