Формирование композита на основе гидрида магния и наноразмерного никеля, полученного методом электрического взрыва проводников

Abstract

The general regularities of hydrogen interaction with nickel nanopowder synthesised for the first time by the method of electric explosion of conductors were studied in this work. Magnesium is one of the most suitable materials for hydrogen storage, the disadvantage of which is its high sorption and desorption temperature. In order to extract hydrogen, high energy must be applied. Therefore, in this work, a composite based on magnesium hydride and nanoscale nickel obtained by electrical explosion of conductors is used as a catalytic additive in the range (1-15 wt%) and synthesis parameters: drum rotation frequency of 900 rpm and synthesis duration of 180 minutes. Thus, a composite based on magnesium hydride and nickel nanopowder was synthesised by planetary ball milling and then the patterns of influence of synthesis parameters and composition of composites on morphology, structural and phase state were established for the obtained composites using SEM and EDS analyses
