Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction [PDF]

Advanced science
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially
