Biosynthesis of nickel oxide (NiO) nanoparticles from cactus plant extract

Muntingia calabura Leaves Mediated Green Synthesis of CuO Nanorods: Exploiting Phytochemicals for Unique Morphology

“…This dilemma paved the way for novel attempts to synthesize CuO NPs using plant extracts as the more sustainable method [11][12][13]. The biosynthesis of different metal oxide nanostructures including nickel oxide [14], cobalt oxide [15], iron oxide [16], and zinc oxide [17] have been reported using various parts of different plant species [18]. To date, a variety of phytochemicals containing plant extracts such as Cordia sebestena flower [19], Rheum palmatum L. root [20], Euphorbia pulcherrima flower [21], and Caesalpinia bonducella seed [22] have been reported for successful synthesis of CuO NPs.…”

Encapsulated MAPbBr3 in nickel oxide nanotubes and their electroluminescence

“…The first one (O 1 ) corresponds to the O anions in NiO lattice and the second (O 2 ) is absorbed oxygen ions in the vicinity of Ni vacancies. 26 Both XRD and XPS studies show that the ZnO template was completely removed from the pNiO x NTs.…”

Biosynthesis of NiO nanoparticles using Spirogyra sp. cell-free extract and their potential biological applications

“…It has been observed that nanoparticles have a spherical shape with some level of agglomeration which might be ascribed to the high surface energy and surface tension of the NiO NPs. 32 Energy dispersive X-ray analysis (EDX) was used to confirm the elemental composition and purity of the NiO nanoparticles. The EDX precisely quantified the Ni and O contents, and exhibited only Ni and O peaks without any other peak due to contaminants (Fig.…”
