Core-shell meso-beta@mesoporous aluminosilicate supported Ni2P catalyst for the hydrodenitrogenation of quinoline: Effect of core shell structure on Ni2P particle size

•Meso-beta@MAS was controllably synthesized through a combination of alkali treatment with self-assembly.•The meso-beta core can provide suitable acidity and the microporous framework can anchor Ni2P particles.•The open wormlike pore structure of MAS shell can make more reactants contact with the Ni2P active species.•The interface of the core–shell structure makes Ni2+ interact more strongly with the support.•Ni2P/meso-beta@MAS core–shell catalyst exhibits high quinoline hydrogenation activity.
