Catalysis

Catalysis is the increase in the rate of a chemical reaction by the addition of a reagent — the catalyst — that is not itself consumed. The catalyst works by opening up a route between starting material and product with a lower activation barrier than the uncatalyzed process.

    Understanding how surface structure affects catalyst selectivity is limited by the ability to synthesize atomically precise active-site ensembles. Now, by using intermetallic Pd–Zn, a series of well-defined multinuclear Pd–metal–Pd catalytic sites have been generated and studied, providing insights into their selectivity for the semi-hydrogenation of acetylene.
