popup.description1
The purpose of scientific research on the topic is to develop the physical and chemical foundations for creating materials for storage of hydrogen in stationary conditions with high hydrogen capacity, reduced thermal stability and fast kinetics of hydrogen sorption-desorption.
popup.description2
It was established that Mg(MgH2) with 10 wt.% Ni, Ti, Fe have a hydrogen capacity of 6.0 wt.%, a reduction in the range of up to 16 times the time of complete release of hydrogen from nanoscale mechanical alloys compared to pure MgH2, which provides the possibility of their practical use for stationary hydrogen storage.
LaNi5-xMx alloys containing Al and Mn have good kinetics of reverse hydrogen absorption, high hydrogen capacity (300 mA*h/g), form stable hydrides, effectively absorb hydrogen during contact charging with Zn. Ternary alloys with Al and Mn can be used for efficient accumulation and storage of hydrogen in the form of a hydride with subsequent use of hydrogen as a gaseous fuel. The effect of the stability of the quantitative phase composition of C15 and C14, which depends on the cooling rate during crystallization, on the properties of the ZrNi1.2Mn0.5Cr0.2V0.1 alloy is shown. The Zr7Ni10 phase speeds up the activation. These materials can be considered for hydrogen storage applications and their use in modern chemical power sources.
The obtained results indicate that efficient hydrolysis performance can be achieved by ball milling of the freshly synthesized MgH2 with 5 wt.% MgCl2 and 1 wt.% TiC–2TiB2 additives. The combination of the applied approaches exhibited a notable synergetic effect on the hydrogen generation.
