Ti based compounds have been reported as excellent catalysts added into other metal hydrogen storage materials to improve the property of release and uptake hydrogen. TiH2 is one of the commonly used catalysts that can significantly reduce the onset temperature of the material to release hydrogen.Therefore, TiH2 is a fascinating hydrogen storage material that deserves further discussion and research. However, regarding TiH2 as a catalyst, no definition or explicit elucidation of its mechanism has been achieved thus far. Meanwhile, ball milling stands as the most commonly employed method for mechanically blending materials and enhancing the performance of hydrogen storage materials. Hence, we conducted a systematic and fundamental study on the effect of ball milling on the performance of TiH2, such as shape, size, material composition, and hydrogen release capabilities.
