| 摘要: 以Cu（NO3）2·3H2O，H2C2O4和Na2S·9H2O为原料，利用简易水热方法合成了笼状硫化铜空心球。所得产物用X射线衍射（XRD）、场发射扫描电子显微镜（FE-SEM）、透射电子显微镜（TEM）和高分辨透射电子显微镜（HRTEM）进行了表征，并研究了其可能的形成机理。所得CuS空心球具有较高的光热转换性能，在近红外光辐照下，对肿瘤细胞具有明显的光热毒性。 |

| Abstract: Cage-like hollow morphologies of copper sulfide nanostructures have been selectively synthesized using cupric nitrate trihydrate (Cu(NO3)2·3H2O), oxalic acid (H2C2O4) and sodium sulphide nonahydrate (Na2S·9H2O) as starting materials in water solution by a self sacrificing templates hydrothermal method. X-ray diffraction (XRD), field scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) were used to characterize the products. The possible formation mechanism of CuS hollow spheres was proposed. The photo-thermal conversion experiments were also done. The results showed that hollow CuS exhibited high photo-thermal efficiency and high anticancer activity under NIR irradiation. |
