Green Synthesis and Characterization of Copper Nanoparticles Using Different Plant Sources

This research aimed at exploring eco-friendly green synthesis of CuNPs using different plant species used for purpose were Nyctanthes arbor-tristris (Night jasmine), Gardenia jasminoides (Cape Tabernaemontana divartica (Crape Cascabela thevetia (Yellow oleander), Clerodendrum inerme (Glory bower), Hibiscus rosa-sinensis (China rose) and Allamanda cathartica (Allamanda) synthesizing CuNPs. Out seven ornamental synthesized from three viz. Night jasmine, Yellow oleander, which confirmed through UV-VIS spectrophotometer in wavelength 250-450 nm. The SPR peak was recorded 301.00 nm, 300.50 nm 300.00 Allamanda, oleander jasmine respectively that the formation FTIR analysis showed functional groups such as O−H, N−H, S−H, O=C=O, C≡C, C=O, N−O, C−H, M−O N≡N, C−Cl C−N, −C≡C−, =C−H, N−O jasmine. DLS study revealed average size 125 120 100 respectively. Zeta potential -13.7 mV, -10.03 mV -12.6 TEM micrograph clearly indicated all spherical morphology 14.05 16.96 11.58 Jasmine
