Therefore, researchers are going for a green synthesis route to prepare nanomaterials because the green synthesis approach is simple, eco-friendly, and cost-effective. However, these methods are not suitable for medicinal and biological applications because of its harmful nature to the environment. Owing to its large surface area, nanomaterial synthesis methods are classified into the physical and chemical methods. Nanomaterials belongs to the range of below 100 nm has unique chemical, physical, electrical, and mechanical properties and also diversely utilized in the field of medical, biotechnology, microbiology, pharmaceutics and chemistry, engineering, inexpensive catalyst, cytotoxicity study, etc. Hence the degradation efficiency and zone inhibition layer indicate that the prepared TiO 2 NPs are the potential candidate for environmental and biomedical applications. The biological activities of green synthesized TiO 2 NPs are enhanced compared to the chemically synthesized TiO 2 NPs. The antibacterial activity of prepared TiO 2 NP’s was studied using grams-positive and gram-negative strains. The Photodegradation study shows the biosynthesized TiO 2 NPs exhibits a higher degradation efficiency compared to chemically synthesized TiO 2 NPs. The Photodegradation of methylene blue dye was investigated and resulted in the maximum degradation efficiency of 92% is achieved at 120 min of irradiation. The obtained results have revealed that the property of TiO 2 nanoparticles was similar in both processes.
The SEM image of TiO 2 NPs reveals that the spherical shaped NPs with randomly arranged manner. The Ti–O–Ti and Ti–O vibration bond formation confirms the formation of TiO 2 NPs. From the UV–Visible spectroscopy, the optically active region of TiO 2 NPs at 385 nm represents the visible region spectrum. The Rutile phase of TiO 2 NPs with an average crystalline size of 31–42 nm was revealed from the XRD pattern. In the green synthesis, jasmine flower extract was used as a reducing and stabilizing agent because it contains alkaloids, coumarins, flavonoids.
The ethanol provoked the chemical reduction of ions.
In this present work, Titanium dioxide nanoparticles (TiO 2 NPs) successfully synthesized using the chemical as well as the green synthesis routine.
