Acetylene Semi‐Hydrogenation by Photocatalysis
Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.Photocatalytic acetylene semi‐hydrogenation is an emerging light‐driven route to polymer‐grade ethylene, offering a mild alternative to energy‐intensive thermocatalysis. By replacing H2 co‐feed with water or other proton sources, these systems can achieve high selectivity under ambient conditions.
