In the present study, the biosynthesis of rutile TiO(2) nanoparticles (TiO(2) NPs) was achieved by a novel, biodegradable and convenient procedure using fruit peel Annona squamosa aqueous extract. This is the first report on the new, simple, rapid, eco-friendly and cheaper methods for the synthesis of rutile TiO(2) NPs at lower temperature using agricultural waste. Rutile TiO(2) NPs were characterized by UV, XRD, SEM, TEM and EDS studies. The UV-Vis spectrophotometer results were promising and showed a rapid production of TiO(2) NPs with a surface plasmon resonance occurring at 284 nm. The formation of the TiO(2) NPs as observed from the XRD spectrum is confirmed to be TiO(2) particles in the rutile form as evidenced by the peaks at 2θ=27.42°, 36.10°, 41.30° and 54.33° when compared with the literature. The TEM images showed polydisperse nanoparticles with spherical shapes and size 23±2 nm ranges.
在本研究中，通过使用水果皮番荔枝水提物的新颖、可生物降解和方便的程序，实现了锐钛矿 TiO(2) 纳米粒子 (TiO(2) NPs) 的生物合成。这是首次报道使用农业废弃物在较低温度下用新的、简单、快速、环保和更便宜的方法合成锐钛矿 TiO(2) NPs。使用 UV、XRD、SEM、TEM 和 EDS 研究对锐钛矿 TiO(2) NPs 进行了表征。紫外-可见分光光度计的结果很有希望，显示出 TiO(2) NPs 的快速生产，其表面等离子体共振发生在 284nm。从 XRD 谱中观察到 TiO(2) NPs 的形成被确认为锐钛矿形式的 TiO(2)颗粒，这可以从与文献比较时的 2θ=27.42°、36.10°、41.30°和 54.33°处的峰得到证明。TEM 图像显示出具有球形形状和 23±2nm 范围的多分散纳米粒子。
