The effect of doping europium, yttrium and lutetium into CeO₂ nanoparticles for the photocatalytic reduction of toxic organic pollutant p-nitrophenol under visible light irradiation was studied. The photocatalysts were synthesized via chemical precipitation method and characterized. The reduction reaction was enhanced by the addition of photocatalysts which was slow only in the presence of NaBH₄ in reducing p-nitrophenol (Yellow) to p-aminophenol (Colourless). Among the synthesized photocatalysts, Lu_0.05CeO₂ showed 96 % efficiency in reducing p-nitrophenol completely within 45 min.

铕、钇、镥掺杂对纳米CeO2可见光还原对硝基苯酚光催化性能的影响

_{研究了在CeO 2}纳米颗粒中掺杂铕、钇和镥在可见光照射下光催化还原有毒有机污染物对硝基苯酚的效果。采用化学沉淀法合成了光催化剂并进行了表征。通过添加光催化剂来增强还原反应，该光催化剂仅在 NaBH ₄存在下才能将对硝基苯酚（黄色）还原为对氨基苯酚（无色）。在合成的光催化剂中，Lu _0.05 CeO ₂在45分钟内完全还原对硝基苯酚的效率为96%。
