Molybdenum-doped TiO2 organic-inorganic hybrid nanoparticles were synthesized under mild hydrothermal conditions by in situ surface modification using n-butylamine. This was carried out at 150 degrees C at autogeneous pressure over 18 h. n-Butylamine was selected as a surfactant since it produced nanoparticles of the desired size and shape. The products were characterized using powder X-ray diffraction, Fourier transform infrared spectrometry, dynamic light-scattering spectroscopy, UV-Vis spectroscopy and transmission electron microscopy. Chemical oxygen demand was estimated in order to determine the photodegradation efficiency of the molybdenum-doped TiO2 hybrid nanoparticles in the treatment of pharmaceutical effluents. It was found that molybdenum-doped TiO2 hybrid nanoparticles showed higher photocatalytic efficiency than untreated TiO2 nanoparticles.
采用正丁胺原位表面改性法，在温和的水热条件下合成了钼掺杂 TiO2 有机-无机杂化纳米粒子。在 150°C 下，自生压力下反应 18 小时。选择正丁胺作为表面活性剂，因为它可以制备出所需尺寸和形状的纳米粒子。通过粉末 X 射线衍射、傅里叶变换红外光谱、动态光散射光谱、紫外-可见光谱和透射电子显微镜对产物进行了表征。为了测定钼掺杂 TiO2 杂化纳米粒子在处理药物废水中的光降解效率，估算了化学需氧量。结果表明，钼掺杂 TiO2 杂化纳米粒子比未处理的 TiO2 纳米粒子具有更高的光催化效率。
