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.

В рамках проведенного исследования был разработан способ модификации материалов на основе гексацианоферратов (III) никеля наноразмерным серебром (ГЦФ Ni–Ag). Гексацианоферрат (III) никеля (ГЦФ Ni) получали методом химического соосаждения в водных растворах. В составе образцов методом порошковой дифрактометрии установлено наличие основной кристаллической фазы гексацианоферрата (III) никеля с кубической гранецентрированной кристаллической решеткой (Fm3m). Для модификации образцы гексацианоферрата (III) никеля доппировали серебром. В качестве прекурсора использовали нитрат серебра, который восстанавливали борогидридом натрия. Методами порошковой дифрактометрии, сканирующей электронной микроскопии и энергодисперсионной рентгеновской спектроскопии установлено, что серебро на поверхности гексацианоферрата (III) никеля находится в аморфной форме и определяется только в образцах ГЦФ Ni–Ag с содержанием серебра 5 масс.% по результатам сканирующей электронной микроскопии и энергодисперсионной рентгеновской спектроскопии.
