Monocarboxylic acid etching strategy: modulation of the chemical environment of Ni nanoparticles in defective Ce-UiO-66 to construct heterogeneous interfaces for dicyclopentadiene hydrogenation

Mesoporous Ce-UiO-66 with abundant missing sites was obtained via acetic acid etching strategy, which can anchor Ni NPs with Ce–O–Ni interfaces, showing high conversion and selectivity in the hydrogenation reaction of dicyclopentadiene.
