In this study, Ag/TiO₂/GO nanocomposites were successfully fabricated by a facile hydrothermal method. Nitrogen-doped GO was prepared using ammonia treatment to improve its conductivity. The Ag/TiO₂/GO nanocomposites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS), zeta potential, and photoluminescence spectroscopy (PL). A homogeneous dispersion of Ag/TiO₂ nanoparticles was shown on the surface of GO. Increasing the nitrogen doping concentration increased hydrophilicity, thereby improving the conductivity of Ag/TiO₂/GO nanocomposites.
在这项研究中，Ag/TiO₂/GO 纳米复合材料通过一种简便的水热法成功制备。使用氨处理制备氮掺杂 GO，以提高其导电性。Ag/TiO₂/GO 纳米复合材料通过扫描电子显微镜 (SEM)、透射电子显微镜 (TEM)、X 射线衍射 (XRD)、紫外-可见漫反射光谱 (DRS)、Zeta 电位和光致发光光谱 (PL)进行了表征。Ag/TiO₂ 纳米颗粒在 GO 表面均匀分散。增加氮掺杂浓度提高了亲水性，从而提高了 Ag/TiO₂/GO 纳米复合材料的导电性。
