Selective Hydrogenation of Formamide to Methanol Over Supported Platinum Catalysts

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Amine–CO2 adducts can be hydrogenated to formamides and subsequently to methanol under mild conditions (<150°C), establishing an integrated CO2 capture‐and‐conversion route in a heterogeneous system that directly links amine sorbent cycling with methanol synthesis.

Consequences of Medium‐Pore Zeolite Constraints for Alkene Cracking—The Case of n‐Pentene

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Alkene cracking in medium‐pore zeolites is governed by a balance of enthalpic and entropic effects. Intrinsic barriers are quantified and shown to be lower than for alkanes due to stabilization of carbenium‐ion‐like transition states. Confinement and extra‐framework aluminum modulate reactivity by tuning transition‐state energetics, providing a ...
