Abstract Fe2O3/ZrO2 nanocomposite photocatalyst was successfully prepared by coprecipitation method for the degradation of diesel pollutants in seawater under visible light. The effects of doping ratio, calcination temperature, photocatalyst dosage, initial diesel concentration, H2O2 concentration, and reaction time on the photocatalytic removal efficiency were investigated. Moreover, the optimal conditions for Fe2O3/ZrO2 nanocomposite photocatalyst to degrade marine diesel pollution were determined. The removal efficiency of diesel by nanocomposite photocatalyst could reach 97.03%. A photocatalyst-loaded polypropylene polyhedral ball was prepared, and the removal efficiency of diesel by photocatalyst-loaded polypropylene polyhedral ball decreased from 99.35 to 68.84% after four recycling cycles.

Fe2O3/ZrO2负载多面体球在可见光下光催化降解海水中柴油污染物的应用

摘要采用共沉淀法成功制备了Fe2O3/ZrO2纳米复合光催化剂，用于可见光下降解海水中的柴油污染物。研究了掺杂比例、焙烧温度、光催化剂用量、柴油初始浓度、H2O2浓度和反应时间对光催化去除效率的影响。此外，还确定了Fe2O3/ZrO2纳米复合光催化剂降解海洋柴油污染的最佳条件。纳米复合光催化剂对柴油的去除效率可达97.03%。制备了负载光催化剂的聚丙烯多面体球，经过4次循环循环后，负载光催化剂的聚丙烯多面体球对柴油的去除效率从99.35%下降到68.84%。
