贺泓院士领衔!中科院生态环境中心徐光艳,最新Angew丨Rh-La双原子调控乙醇重整产氢!
Merged summary
TL;DR - An Angewandte Chemie study reports adjacent Rh-La dual-atom sites that coordinate ethanol activation and water dissociation, enabling more efficient hydrogen production from ethanol steam reforming.
- Rh cleaves ethanol C-C bonds, while oxophilic La activates water and stabilizes carboxylate intermediates.
- Electronic coupling shifts the water-gas shift reaction from a high-barrier redox route to a lower-barrier carboxylate pathway.
- The catalyst achieved a hydrogen production rate of 80.5 L g⁻¹ h⁻¹ with sustained activity and reduced carbon deposition.
- Similar benefits in Pd-La, Pt-La, and Ir-La systems suggest the dual-atom strategy is broadly applicable.
