| Resumo: | This study explores Liquid Organic Hydrogen Carriers (LOHCs) like benzyltoluene as a promising alternative for efficient hydrogen storage. In response to the common use of noble metal-based catalyst in the literature, this work focuses on the synthesis of cost-effective Ni-based formulations with small quantities of PGMs. The prepared Ni catalyst exhibited outstanding hydrogenation performance with a hydrogenation yield ∼100 % within 3 h. Furthermore, the incorporation of mall amount (0.5 wt%) of Pt into the catalysts proved to boost the hydrogenation activity due to synergistic Pt–Ni interactions. This study underlines the potential of PtNi bimetallic catalysts as high-performance formulations, contributing to the development of economically viable and efficient catalyst for H2 storage via LOHCs. |
