Comparative study of hydrogen storage on metal doped mesoporous materials
(Elsevier Science, 2018-04-18)
The hydrogen adsorption capacity of mesoporous materials MCM-41 modified with Co, Fe, Ti, Mg and Ni at 77 K and 10 bar was investigated. Various techniques including XRD, N2 adsorption and DRUV–vis were employed for the ...
A new model for the prediction of oxygen interference in hydrogen storage systems
(Pergamon-Elsevier Science Ltd., 2014-04)
A new model is developed to analyze oxygen interference in hydrogen storage materials. It is based on the competitive adsorption isotherm between the two gases, with the parameters fitted from molecular dynamic simulations. ...

(Elsevier B.V., 2014-03-06)
It is feasible to obtain a significant enhancement of the hydrogen storage capability in magnesium by selecting an appropriate sequence of mechanical processing. the Mg metal may be produced with different textures which ...
Graphene entanglement in a mesoporous resorcinol-formaldehyde matrix applied to the nanoconfinement of LiBH4 for hydrogen storage
(Royal Society of Chemistry, 2017-05)
A new, easy and versatile method for graphene inclusion within resorcinol-formaldehyde is presented and applied to the nanoconfinement of LiBH4. After the initial formation of a graphene hydrogel, the resin precursors were ...
Mechanochemical synthesis of erbium borohydride: Polymorphism, thermal decomposition and hydrogen storage
(Elsevier Science, 2013-12)
A new erbium borohydride Er(BH4)3 was synthesized from 3LiBH4 and ErCl3 through mechanochemical processing. This rare-earth metal borohydride presents a primitive cubic structure with a = 10.74(1) Å, which is isostructural ...
Understanding the role of nickel on the hydrogen storage capacity of Ni/MCM-41 materials
