Ag₂O/GO/TiO₂ composite nanoparticles were synthesized via a two-stage route including wet chemical and sol-gel techniques. The phase regarding the composition and morphology of composite nanoparticles was characterized using X-ray diffraction (XRD), Fourier transfer infrared (FT-IR) spectroscopy, and field emission scanning electron microscopy (FESEM). The structural studies revealed the successful formation of 300-nm Ag₂O/GO/TiO₂ composite spheres self-assembled to 35-nm particle aggregates. UV-Vis diffuse reflectance spectroscopy (DRS) was utilized to investigate optical properties. The results indicated an absorption edge in the UV region with a band-gap equivalent to 3.2 eV for Ag₂O/GO/TiO₂ composite nanoparticles. The morphological features of the sample were investigated with a Zeiss (EM10C, Germany) transmission electron microscope (TEM) operating at 100 kV.

Ag ₂ O / GO / TiO ₂复合纳米粒子是通过两步法合成的，包括湿法化学法和溶胶-凝胶法。使用X射线衍射（XRD），傅立叶转移红外（FT-IR）光谱和场发射扫描电子显微镜（FESEM）表征了有关复合纳米颗粒的组成和形态的相。结构研究表明，成功组装了300nm的Ag ₂ O / GO / TiO ₂复合球，这些球自组装成35nm的颗粒聚集体。紫外-可见漫反射光谱法（DRS）用于研究光学性质。结果表明，对于Ag ₂ O / GO / TiO ₂，UV吸收边缘的带隙等于3.2 eV复合纳米颗粒。用在100 kV下操作的Zeiss（德国EM10C）透射电子显微镜（TEM）研究了样品的形态特征。
