The article discusses the importance of large-scale storage and transportation of hydrogen for building a sustainable society based on hydrogen energy. It highlights the use of liquid organic hydrogen carriers (LOHC), specifically the hydrogenation-dehydrogenation cycle between toluene (TOL) and methylcyclohexane (MCH), as a promising route for implementation. The focus is on developing efficient catalysts for each step of the production chain, emphasizing the dehydrogenation of MCH to TOL as a critical step in the process. The article introduces a highly efficient supported Pt catalyst for MCH dehydrogenation by incorporating subnanometer bimetallic PtFe clusters within a zeolite matrix, ensuring stability and high performance. Results show the catalyst's highest reaction rate, chemoselectivity to toluene, stability over 2000+ hours, and purity exceeding 99.9% in hydrogen production, essential for fuel cells. By utilizing Pure-silica MFI-type zeolite as a host for subnanometer metal species, the catalyst achieves effective confinement and stability during the dehydrogenation reaction, presenting a significant advancement in green hydrogen storage and transportation.
