A catalytic mechanism investigation of TiF 3 on hydriding/dehydriding properties of Mg 85 Cu 5 Ni 10 alloy
In this research, Mg Cu Ni - wt% TiF ( = 0, 2, 4, 6, 8) alloys were synthetized ball milling and the catalytic mechanism of TiF on hydrogenation and dehydrogenation of Mg Cu Ni was studied. The microstructure, hydriding/dehydriding kinetics and thermodynamics of the alloys were discussed in detail....

(

ball milling and the catalytic mechanism of TiF
on hydrogenation and dehydrogenation of Mg
Cu
Ni
was studied. The microstructure, hydriding/dehydriding kinetics and thermodynamics of the alloys were discussed in detail. The TiF
catalyzed alloys have faster hydriding/dehydriding kinetics and lower thermodynamic stability. After hydrogen absorption and desorption, TiF
decomposes into TiH
and MgF
. TiF
, TiH
and MgF
promote to forming crystal defects, dislocations, grain boundaries and nanocrystals which are advantageous to speeding up the rate of hydrogen absorption and desorption. The dehydrogenation activation energy
(de) and dehydrogenation enthalpy Δ
(de) are reduced to 81.462 from 116.767 kJ mol
and 72.456 from 93.372 kJ mol
respectively by 6 wt% TiF
. An appropriate amount of TiF
can improve the hydriding/dehydriding kinetics and thermodynamics of Mg
