Improved dehydrogenation/rehydrogenation performance of LiBH4 by doping mesoporous Fe2O3 or/and TiF3

The LiBH 4 + mesoporous Fe 2 O 3 (defined as M-Fe 2 O 3 ) mono-doped and LiBH 4 + M-Fe 2 O 3 + TiF 3 co-doped hybrid materials were prepared by ball milling process. A variety of characterization methods, such as thermogravimetric, differential scanning calorimetry, X-ray diffraction, and pressure–composition–temperature instrument, were used for examinations of the two materials’ performances of storage/release of hydrogen, catalytic activity, kinetics, and thermodynamics. All the results showed that the M-Fe 2 O 3 prepared in laboratory exhibited a good catalytic effect. Compared with the performance of M-Fe 2 O 3 mono-doped system, M-Fe 2 O 3 and TiF 3 co-doped mode exhibits a better performance using the same additive content. Thus, the M-Fe 2 O 3 and TiF 3 co-doped mode possesses a collaborative catalytic utility with the LiBH 4 hydrogen performance improved, showing a promising application.
