Влияние содержания никеля на температуру десорбции водорода из композита на основе гидрида магния и наноразмерного никеля, синтезированного методом электрического взрыва проводников

Abstract

The general regularities of hydrogen interaction with nickel nanopowder synthesised for the first time by electric explosion of conductors are studied in this work. Magnesium is one of the most suitable materials for hydrogen storage, the disadvantage of which is the high temperature of sorption and desorption. High energy must be applied to extract hydrogen. Therefore, in this work, a composite based on magnesium hydride and nanoscale nickel obtained by electrical explosion of conductors was used as a catalytic additive in the range (1-25 wt.%) and synthesis parameters: drum speed of 900 rpm and synthesis duration of 180 minutes. Thus, the composite based on magnesium hydride and nickel nanopowder was synthesised by planetary ball milling and then thermodesorption was carried out for these composites and the hydrogen yield teperature of the composites was determined
