Structural isomerism in Ce-MOFs directs Ni/CeO 2 catalyst design for selective fatty acid deoxygenation to linear α-olefins

We report a structural isomerism engineering of Ce-MOF precursors to design Ni/CeO₂ catalysts featuring abundant oxygen vacancies and highly dispersed Ni⁰ sites, enabling complete conversion of stearic acid with 82.4% selectivity toward linear α-olefins. Mechanistic studies reveal a synergistic interplay between oxygen vacancies and Ni sites.
