The effect of isolation: Well-dispersed Ni–Ga intermetallic compounds with tunable particle size demonstrate excellent catalytic behavior in the selective hydrogenation of phenylacetylene to styrene. X-ray absorption fine-structure characterization and DFT calculations reveal the electron transfer and active-site isolation effect in the Ni–Ga intermetallic compounds (IMCs), accounting for the enhanced hydrogenation selectivity.
