In Situ Formed Pt–Ga Hetero Duo-Atomic Catalyst for Efficient Hydrogen Storage in N-Heterocycles
Efficient catalysts for the dehydrogenation and hydrogenation of liquid organic hydrogen carriers (LOHCs) are essential for advancing hydrogen storage and transportation. Conventional nanoparticle catalysts suffer from low metal utilization, while single-atom catalysts (SAC) are limited by isolated active sites. Here, we present a hetero duo-atomic catalyst, Pt<sub>1</sub>-Ga<sub>1</sub>/CeO<sub>2</sub> DAC, which exhibits exceptional activity, selectivity, stability, and recyclability for N-heterocycle hydrogen storage. Ga plays a critical role in C-H bond activation, acting as a mediator in catalytic bond-breaking and formation. Compared with Pt<sub>1</sub>/CeO<sub>2</sub> SAC, Pt<sub>1</sub>-Ga<sub>1</sub>/CeO<sub>2</sub> DAC enhances metal utilization while overcoming SAC limitations for large substrates. This work establishes a promising strategy for designing highly efficient catalysts for LOHC applications.
