ZnO nanoparticles (NPs) with a granular morphology were synthesized using a hydrothermal method. Structural analysis revealed that ZnO NPs had a single crystal wurtzite hexagonal structure. Solvent polarity was responsible for varying and controlling their size and morphology. The process was very trouble free and scalable. In addition, it could be used for fundamental studies on tunable morphology formation. This hydrothermal method showed different morphology with different co-surfactants such as a floral-like or wire-like belt sheet structures etc. Based on their surface morphology, the same material had different applications as a catalyst in various organic reactions and also could be used as a photocatalyst and fuel cell, solar cell or in semiconductors etc. X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible spectroscopy and photoluminescence of the resulting product was performed to study its purity, morphology and size, plus its optical properties via measurement of band gap energy and light absorbance.
采用水热法合成了具有颗粒形态的氧化锌纳米颗粒（NPs）。结构分析表明，氧化锌纳米颗粒具有单晶纤锌矿六方结构。溶剂极性决定了它们的尺寸和形态的变化与控制。该过程非常简便且可扩展。此外，它可用于可调形态形成的基础研究。这种水热法在使用不同的共表面活性剂时会呈现出不同的形态，如花朵状或线状带状片状结构等。基于其表面形态，相同的材料在各种有机反应中作为催化剂有不同的应用，还可作为光催化剂、燃料电池、太阳能电池或用于半导体等。对所得产物进行了X射线衍射（XRD）、扫描电子显微镜（SEM）、紫外可见光谱和光致发光分析，以研究其纯度、形态和尺寸，以及通过测量带隙能量和光吸收率来研究其光学性质。
