Coordinatively unsaturated aluminum anchored Ru cluster for catalytic hydrogenation of benzene

u  Amorphous alumina with 62% penta-coordinated Al³⁺ was prepared via solution combustion synthesis.

u  With Ru loading of 1 wt%, high dispersion was obtained (Particle size of 0.93 nm).

u  High TOF (5 times higher than commercial catalyst) of hydrogenation of benzene was achieved.

       u  DFT calculation suggest Ru₂/ Al³⁺_penta site is the most stable configuration over Ru/CUA.

       u  Ru₂/ Al³⁺_penta with high adsorption energy of benzene exhibits high catalytic activity.

uThis strategy is also applicable to the dispersion of Pd catalyst.
