چکیده مقاله:
In this study, green or eco-friendly synthesis of TiO۲ nanoparticles (NPs) was performed by using the aqueous extract of Acanthophyllum laxiusculum. The plant genus Acanthophyllumis one of the natural sources rich in nonionic surface active agents known as saponins. Sol-gel method as one of the most common techniques widely used in nano-field was applied to synthesize the titanium dioxide nanoparticles. TiO۲ nanoparticles were characterized by X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM) and Energy Dispersive Analysis of X-rays (EDAX). Fourier Transform Infrared Spectroscopy (FTIR) was performed to confirm the lack of the surfactant templates in synthesized NPs. The optical band gap of synthesized TiO۲nanospheres was determined using UV–Vis absorption spectra and further verified by diffuse reflectance spectroscopy analysis. The specific surface area and pore size distribution of this product were evaluated by employing the Brunauer– Emmett–Teller (BET) technique and the Barrett–Joyner–Halenda (BJH) model.
