Synthesis of cerium oxide nanoparticles using Gloriosa superba L. leaf extract and their structural, optical and antibacterial properties

A Green Strategy to Synthesize Environment Friendly Metal Oxide Nanoparticles for Potential Applications – A Review

“…As reported, the metal oxide NPs synthesized through green synthesis exhibit almost spherical which gives better application in various fields [22,23,44,55]. Granular-shaped NPs were obtained while they used M. oleifera as a green extract with ZNO material [56].…”

“…It provides information that reduction decreases the d-spacing toward 0.850 nm [25]. Cerium oxide possesses face-centered structure [22], iron oxide possesses orthorhombic structure [29], and Titanium oxide possesses cubic structure. [39].…”

“…A white precipitate was obtained and it changed to yellowish brown on continuous stirring. The obtained precipitate was calcined at 400°C for 2 hrs [22]. A. linearis leaves were added into deionized water at a temperature between 75°C and 85°C for 2-3 hrs yielding a brown [17] extract (pH=5).…”

“…The optical absorption spectra of NPs are well known to exhibit unique optical properties due to the property of surface plasmon resonance (SPR); the change in the transition of cerium ions plays an important role in the increase in the band gap of cerium oxide NPs [22]. The spectrum of GO showed that peak around at 230 nm and at 300 nm indicates the presence of GO [25].…”

Synthesis and Characterization of Various Metal Ions Doped CeO2 Nanoparticles Derived from the Azadirachta Indica Leaf Extracts

“…The enhancement of ROS yields may be connected with the electronic properties and microstructure (i.e., grain size, specific surface area and pore, etc.) of the nanostructure 19 …”
