SILVER-DOPED NICEL HEXACYANOFERRATE (III) AS A MATERIAL FOR CREATING GLUCOSE SENSORS
SILVER-DOPED NICEL HEXACYANOFERRATE (III) AS A MATERIAL FOR CREATING GLUCOSE SENSORS
DOI: https://doi.org/10.22184/1993-8578.2025.18.7-8.440.448
As part of the study, a method for modifying materials based on nickel hexacyanoferrates (III) with nanoscale silver (HCF Ni–Ag) was developed. Nickel (III) hexacyanoferrate (HCF Ni) was obtained by chemical co-precipitation in aqueous solutions. The presence of a basic crystalline phase of nickel (III) hexacyanoferrate with a cubic face-centered crystal lattice (Fm3m) was found in the samples by powder diffractometry. For modification, nickel hexacyanoferrate (III) samples were doppled with silver. Silver nitrate, which was reduced with sodium borohydride, was used as a precursor. It has been established by powder diffractometry, scanning electron microscopy, and energy-dispersive X-ray spectroscopy that silver on the surface of nickel (III) hexacyanoferrate is in an amorphous form and is detected only in Ni–Ag HCF samples with a silver content of 5 wt.% based on the results of scanning electron microscopy and energy dispersive X-ray spectroscopy.
