Abstract:
Hydrothermal synthesis stands out as a highly effective method for creating nanostructures
due to its eco-friendly and straightforward process. In this study, we successfully produced sodium ni
trate and nickel (II) chloride nanoparticles using hydrothermal methods. Sodium nitrate (NaNO3) and
nickel (II) chloride hexahydrate (NiCl2·6H2O) were synthesized through precise chemical methods. The
resulting samples underwent thorough characterization and analysis using a range of advanced techniques,
including UV–visible spectroscopy, microscopic analysis, FTIR, anti-bacterial activity testing, zeta poten
tial measurement and SEM. The UV–visible spectroscopy results confirmed that the synthesized bimetallic
Na–Ni nanoparticles possessed a size range of 300–600 nm. FTIR analysis identified the functional groups
of the bimetallic Na–Ni nanoparticles, with peaks at 2853.016, 2080.025, 1607.706, 1363.261 and 834.847
cm−1, corresponding to C–H stretching, C=O stretching, N–H bending, O–H bending and C–H bending.
Anti-bacterial activity tests demonstrated the effectiveness of the synthesized bimetallic Na–Ni nanoparti
cles against Gram-positive (Staphylococcus aureus) and Gram-negative (Pseudomonas aeruginosa) bacterial
strains. Additionally, the study decisively showcased the capabilities of these bimetallic nanoparticles in
dye degradation. Our findings revealed that these bimetallic nanoparticles can efficiently remove pollutants
from highly contaminated water, rendering the treated water suitable for various applications, including
agricultural use. Furthermore, we rigorously evaluated their performance as fertilizers. In seed germination
experiments, they affirmed their potential in sustainable agriculture.
