СТРУКТУРНЫЕ ОСОБЕННОСТИ БИМЕТАЛЛИЧЕСКОГО ЭЛЕКТРОКАТАЛИЗАТОРА ФОСФИДА Ni-Co-P, ПРЕДНАЗНАЧЕННОГО ДЛЯ ГЕНЕРАЦИИ ВОДОРОДНОГО ТОПЛИВА

Background. To decompose water, electrocatalysts based on expensive Pt, Ir are used. However, there is an alternative - catalysts from compounds of d-elements: Fe, Co, Ni, Cu. Purpose. Study of structural morphology features of Ni-Co-P bimetallic phosphide.. Methodology. The synthesis of Ni-Co-P was carried out by a one-stage hydrothermal method, in air. The structure of the sample was studied by electron microscopy (SEM), energy-dispersive spectroscopy, and X-ray diffractometry. Originality. It was revealed that the synthesized Ni-Co-P has a pronounced crystal structure of the compounds Ni2P4O12 (59%), NiP2O7 (37%) and NiCoP (4%). Findings. The synthesis of Ni-Co-P was carried out. The phase composition, morphology of the surface and crystal structure, the nature of the distribution of elements over the volume of Ni-Co-P bimetallic phosphide were studied by physicochemical methods of analysis.
