  Abstract

The utilization of renewable energy and the development of low-carbon technologies are gaining attention in response to climate change. This study synthesized TiNi catalysts to mitigate the intermittency problems associated with renewable energy and improve the hydrogenation characteristics of MgH2, which can safely store hydrogen. In addition, the catalyst was dispersed with graphene oxide to reduce aggregation and the catalyst’s properties were evaluated. XRD, SEM, and BET analyses were performed to confirm the metallurgical properties of the hydrogen storage composite, and PCT (pressure-composition-temperature) was used to observe the hydrogen adsorption behavior. The results showed that the hydrogen adsorption rate of MgH2 was improved when more than 10 wt% TiNi was used as a catalyst, and the hydrogenation reaction rate was improved when 5 wt% graphene oxide was added. Therefore, the effect of graphene oxide on reducing the aggregation phenomenon of TiNi catalyst was confirmed.
