Description
Zewei Dou and six co-authors present a 2026 chemistry study that overturns a common view of gold catalysts. The reaction at stake joins acetylene and hydrogen chloride, a step used in industry. Gold catalysts for it are made from a gold chloride mix, so gold bound to chlorine was long thought to be the active form.
The team found the reverse. Gold with no chlorine bond was highly active, even at room temperature. Activity fully vanished when just a small share of the gold bound chlorine. Lab work and theory together explain why. The result matters because the reaction gives off much heat and plants now run it hot. A catalyst that works cool could cut hot spots, wear, and rust from the acid feed.
