The LiBH4?+?mesoporous Fe2O3 (defined as M-Fe2O3) mono-doped and LiBH4?+?M-Fe2O3?+?TiF3 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-Fe2O3 prepared in laboratory exhibited a good catalytic effect. Compared with the performance of M-Fe2O3 mono-doped system, M-Fe2O3 and TiF3 co-doped mode exhibits a better performance using the same additive content. Thus, the M-Fe2O3 and TiF3 co-doped mode possesses a collaborative catalytic utility with the LiBH4 hydrogen performance improved, showing a promising application.
