Structure and hydrogen storage properties of MgH2 catalysed with La2O3

Hydrogen Sorption Behaviors of a Core–Shell Structured Mg@Fe Composite Powder

“…Our experimental results clearly showed that the ¡-Fe shell played a catalytic role for improving the hydrogen sorption kinetic properties of the Mg core particles. During the re-/dehydrogenation, like other catalysts, such as Nb 2 O 5 , La 2 O 3 etc., 21,22) nano ¡-Fe covered on the Mg particles can act as channels for hydrogen absorption and desorption, and thereby improve significantly the hydrogen sorption kinetics of Mg.…”

Preparation and hydrogen sorption properties of a nano-structured Mg based Mg–La–O composite

“…Considering the above factors, one can safely draw a conclusion that La 2 O 3 must play a catalytic role for the hydrogen sorption of Mg in the composite. Indeed, La 2 O 3 has been found to be a good catalyst for hydrogen sorption in Mg which can i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 7 ( 2 0 1 2 ) 1 3 0 6 7 e1 3 0 7 3 improve the kinetics of hydrogen desorption [10]. It is known that the dissociation of hydrogen molecules requires a fairly high energy on the Mg surface [6].…”

Adsorption, reduction and storage of hydrogen within ZSM-5 zeolite exchanged with various ions: A comparative theoretical study

“…On such basis, we predict that the La III ion should be a good candidate for hydrogen storage. As a matter of fact, the La III ion has ever been used as an additive for hydrogen storage materials [68,69]. As the La content is low for ZSM-5 zeolite with high Si/Al ratios, the weight of La cations is not so crucial with respect to the zeolite systems and storage capacity.…”
