摘要: In this study, CeO2 and a mixture of TiO2 (CeO2-TiO2, Ce: Ti (mol.) = 3: 1) were synthesized by the solvothermal method at different temperatures. The particle size, either or CeO2-TiO2 140 °C was less than 10 nm. Nitrogen carbon co-doped using hexamethylenetetramine (HMT) as precipitator °C. degradation ratio acid orange 7 (AO7) could achieve 98.8% with under an irradiation Watt compact fluorescent lamp (CFL). degrade 93.3% AO7 CFL. contrast, only reached 43.0% TiO2. However, result Na2CO3 gave 5.0%, i.e., 94.9% reduction compared that HMT precipitator.
