Summary: Adding 10wt% spherical SrTiO3 catalyst can decrease the onset desorption temperature and enhance the desorption kinetics of NaAlH4. The decrease in apparent activation energy and improvement in desorption properties of NaAlH4 are attributed to the reduction of the physical structure of NaAlH4 by SrTiO3 during ball milling.

Summary: With increased development and electricity generation, it is crucial to consider energy storage systems to overcome the discontinuity in renewable production. Hydrogen is an ideal energy carrier for future mobility, such as automotive applications. However, current hydrogen storage materials do not meet all requirements in terms of storage capacity and commercialization. Developing new materials with large surface area, homogeneous texture, active-conductive profiles, large oxygen vacancies, and low cost is crucial. Multiphase materials composed of these materials can meet the requirements in this field.
