Oil bath approach of nickel phosphate (Ni3 (PO4)2) nanocrystal and their structural and functional properties
This research work describes the synthesis and characterization of nickel phosphate (NiPO) nanostructures, which were successfully synthesized by the simple oil bath technique. X-ray diffraction, Fourier transform infrared spectroscopy and thermal gravimetric–differential thermal analysis were used to analyse the product's structure, functional groups and thermal stability. It was determined that the produced substance had a monoclinic structure. Perfectly spherical Ni3 (PO4)2 nanoparticles with a diameter of around 12 nm were seen using transmission electron microscopy. Using the cyclic voltammetry method, the capacitive properties of NiPO were assessed between − 1.4 and 1.6 V in a 2 M tetrabutylammonium cation (TBA+) electrolyte. A NiPO nanocrystal at 5 mV/s has significant pseudocapacitances of around 673F/g. Additionally, the antibacterial mechanisms of NiPO nanocrystal against Escherichia coli (E. coli) were evaluated by agar well diffusion and systematically analysed by measuring the diameter of the inhibition zone. Mean diameter of inhibition zone was observed to be 2.1 ± 0.5, 5.3 ± 1.4, 9.2 ± 0.7, 12.4 ± 0.8 and 15.5 ± 0.6 for 20, 40, 60, 80 and 100 μg/mL concentration of NiPO nanocrystal. It is possible to use the inexpensive and environmentally friendly synthesis of NiPO nanomaterial as an efficient antibacterial agent. © The Author(s), under exclusive licence to the Institute of Chemistry, Slovak Academy of Sciences 2025.
