Light‐Promoted Hydrazine Dehydrogenation over Ni/NH2‐MIL‐125: Unraveling Mechanisms for Efficient Hydrogen Production

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
Highly dispersed and electron‐rich Ni nanoparticles (≈2.7 nm) supported on NH2‐MIL‐125 significantly promote the dehydrogenation of hydrous hydrazine under visible‐light irradiation, achieving a turnover frequency of 220.2 h−1 at 323 K, which is more than twice that in the dark (108.1 h−1) and outperforms most reported non‐precious metal catalysts ...

Redox‐Active Frustrated Lewis Pair‐Mediated B─H Bond Activation: From Proton Transfer to THF Ring Opening

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
Carbene‐stabilized dithiolene zwitterion, as a redox‐active frustrated Lewis pair, can mediate the B─H bond activation of catecholborane via hydride‐coupled reverse electron transfer processes. This discovery represents the first experimental evidence of the FLP‐mediated B─H activation via net proton transfer.
