Abstract: High Resolution Image Download MS PowerPoint Slide Porous materials play a pivotal role in engineering catalytic systems for efficient and sustainable hydrogen release from Liquid Organic Hydrogen Carriers (LOHCs), a critical vector in clean energy and decarbonization strategies. This review highlights advances in porous-supported catalysts (encompassing γ-/η-Al 2 O 3, mesoporous silica, carbon frameworks, and Mg/Al layered oxides) that facilitate precise control over catalyst morphology, metal dispersion, and interfacial chemistry. We examine monometallic (Pt, Pd, Ir) and bimetallic (Pt–Sn, Pt–Pd, Pt–Ir) systems, elucidating how d-band theory, Brønsted–Evans–Polanyi (BEP) relationships, and strong metal–support interactions (SMSI) govern hydrogen desorption, coke resistance, and structural stability. Special focus is placed on engineering supports to modulate acidity, enhance site isolation, and promote selective C–H activation under mild operating conditions. By integrating atomic-scale insights with mesostructural engineering, this review proposes a rational framework for designing robust, regenerable dehydrogenation catalysts that advance LOHC technology for biomaterial-compatible hydrogen storage and green energy integration.
