Description
Xianhui Wang and colleagues describe a relay route for adding hydrogen to acetylene in 2026, a key step in making ethylene for plastics. Single palladium atoms sit on alumina, a support long seen as inert for this move. Phosphorus sites on the support form a bridge that passes hydrogen along.
Lab spectra, rate tests, and computer models trace the hand off step by step. Gas hits the bridge site head on, so the support itself does part of the work. Palladium use fell ten fold while the yield held strong. More than 95 percent of product was ethylene at near full conversion for over 200 hours.
