Photocatalytic degradation of municipal wastewater was investigated using reagent grade TiO(2) and modified neodymium doped TiO(2) hybrid nanoparticles. For the first time, surface modification of Nd(3 +) doped TiO(2) hybrid nanoparticles were carried out with n-butylamine as surface modifier under mild hydrothermal conditions. The modified nanoparticles obtained were characterized by Powder XRD, FTIR, DLS, TEM, BET surface area, zeta potential and UV-Vis Spectroscopy. The characterization results indicated better morphology, particle size distribution and low agglomeration of the nanoparticles synthesized. It was found that photodegradation of wastewater using surface modified neodymium doped TiO(2) nanoparticles was more compared to pure TiO(2), which can be attributed to the doping and modification with n-butylamine.
采用试剂级 TiO(2) 和改性钕掺杂 TiO(2) 杂化纳米粒子研究了城市废水的光催化降解。首次在温和水热条件下，用正丁胺作为表面改性剂对 Nd(3+)掺杂 TiO(2) 杂化纳米粒子进行了表面改性。用粉末 XRD、FTIR、DLS、TEM、BET 表面积、zeta 电位和 UV-Vis 光谱对所得改性纳米粒子进行了表征。表征结果表明，所合成的纳米粒子具有更好的形态、粒径分布和低团聚。研究发现，使用表面改性的钕掺杂 TiO(2) 纳米粒子进行光降解废水的效果比纯 TiO(2) 更好，这可以归因于掺杂和用正丁胺改性。
