Structural characterizations of as-synthesized ZnO-NRs (A) XRD pattern of as-synthesized ZnO-NRs was recorded with the 2Ø angle in range of 20–80. XRD pattern of NRs showed well-resolved diffraction peaks of the crystalline structure. (B) Representative FTIR spectrum of the as-synthesized ZnO-NRs. (C) UV–visible absorption spectrum of as-synthesized ZnO-NRs fabricated by employing egg white as bio template. (D) Tauc plot representing the energy band gap of as-synthesized ZnO-NRs.
