TL;DR: In this paper, the efficiency of Nb2O5 as a catalyst for hydrogen sorption reaction of magnesium is investigated, and the results demonstrate that the catalytic effect of the catalysts is superior in absorption as well as desorption.

TL;DR: In this paper, the effect of Nb 2 O 5 concentration on the kinetics of the magnesium hydrogen sorption reaction at 300°C and 250°C was investigated, and the results showed that there is a change in the rate-limiting step with catalyst content.

TL;DR: A detailed analysis of the reaction mechanism of the reactive hydride composite (RHC) was performed using high-pressure differential scanning calorimetry (HP-DSC) measurements and in situ synchrotron powder X-ray diffraction (XRD) measurements along with kinetic investigations using a Sievert-type apparatus as discussed by the authors.

TL;DR: In this article, the effect of various reactants on the formation kinetics of complex borohydrides is investigated, and it is found that the kinetic barriers for the formation of LiBH 4, NaBH4 and Ca(BH 2 ) 2 are drastically reduced when MgB 2 is used instead of B as starting material.

TL;DR: In this paper, the effect of milling time and Nb 2 O 5 content on the magnesium hydrogen sorption reaction was investigated and the rate-limiting step of the absorption and desorption reactions was determined by fitting the respective kinetic equations.
