Superior catalytic effect of TiF3 over TiCl3 in improving the hydrogen sorption kinetics of MgH2: Catalytic role of fluorine anion

The effects of Ti-based additives on the kinetics and reactions in LiH/MgB2 hydrogen storage system

“…The phenomenon of hydrogenation agrees well with that presented in Fig. 2 where the onset temperatures of TiF 3 and TiCl 3 doped mixtures are [7,22] or MgH 2 [23] system. The times to full dehydrogenation are 4000 s and 6000 s respectively.…”

Nanolayer-like-shaped MgFe2O4 synthesised via a simple hydrothermal method and its catalytic effect on the hydrogen storage properties of MgH2

“…Data were collected in the 2q range 20 to 80 at 2 min À1 . The morphologies of the samples were observed by scanning electron microscopy (SEM) (JEOL JSM-6350LA).…”

“…However, MgH 2 is restricted by the decomposition temperature, which is high with slow sorption kinetics and is excessively stable thermodynamically. 2 Many research have been conducted to overcome these disadvantages by altering the thermodynamics and improve the kinetic properties by producing nanostructures 3,4 and utilizing catalysts such as carbon-based materials, 5,6 metals, 7-10 metal hydrides, 11,12 metal oxides, [13][14][15][16][17][18] metal halides, [19][20][21] and nanosized alloys.…”

Mechanism and kinetics of early transition metal hydrides, oxides, and chlorides to enhance hydrogen release and uptake properties of MgH2

“…Moreover, halides of Fe, Ni, and Nb have also shown attractive catalytic properties (Ivanov et al, 2003;Deledda et al, 2005;Bhat et al, 2006;Kim et al, 2008;Ma et al, 2009).…”
