“…The computed band gaps using Tauc plots for ZnO were 3.34 eV, and 3.30 eV for the OPE, and LPE BiONPs, respectively. These values are comparable with that of their monoxide counterparts [30,42]. Using the same Tauc plot, the computed band gap for CuO were 2.44 eV, and 2.45 eV and are consistent the band gap values of Cu 2 O reported in another work [48].…”

“…The bioxide NPs were prepared by simple bioreduction method using citrus peels extracts in an alkaline medium. The preparation of the orange and lemon peels extract used (OPE and LPE, respectively), have been detailed in our previous works [ 30 , 42 ]. In total, 0.1 M (100 mL) each of the precursors salts, Cu(NO 3 ) 2 and Zn(NO 3 ) 2 were added at the same time into two different conical flask of appropriate volume and heated above 90 °C under a magnetic stirring.…”

“…The extraction of the citrus peels followed the procedure described in our previous work [ 35 ] and another literature report [ 36 ]. The filtrate was later kept in the refrigerator for subsequent use.…”

“…In addition, microorganisms, e.g., yeast, bacteria, and fungi have been utilized to prepare CuO NPs in the literature [30,31]. To date, there has been an increase in reports on the synthesis of CuO NPs using plant extracts such as Gloriosa superba L., Aloe Vera leaf, coffee powder, and fruit peel extract [23,[32][33][34]. Thus, green synthetic CuO NPs using plant extracts are considered a good alternative to hazard reagents, high costs, and time-consuming methods.…”
