Green Synthesis of Nickel and Copper Nanoparticles Doped with Silver from Hammada scoparia Leaf Extract and Evaluation of Their Potential to Inhibit Microorganisms and to Remove Dyes from Aqueous Solutions

Hammada scoparia (Pomel) is a powerful plant with important biological properties. In this study, we report on the green synthesis of silver-doped nickel and copper nanoparticles (NPs) in presence H. leaf extract using self-propagating sol–gel autocombustion process. The synthesized NiO, CuO, Ag-NiO, Ag-CuO NPs were characterized Fourier transform infrared spectroscopy (FTIR) X-ray diffraction (XRD). Afterward, they tested for their antimicrobial activity as well potential to remove dyes from aqueous solutions adsorption processes malachite (MG) photocatalytic degradation methylene blue (MB). Our results showed that mass adsorbent had significant effect rate, which increased reach maximum value 98%. NP best final conversion MB (97.95%) compared Ag-NiO. addition, noted doped silver performance removal dyes. These indicated was significantly improved after addition silver. Moreover, studied moderate against bacteria weak or ineffective Candida albicans. Therefore, considered sustainable alternative removing solutions. However, further investigation should be performed other understand overall effectiveness these NPs.
