They combined ammonia and water to produce nitrite and hydrogen, using a multi-metal catalyst on Ni foam, with Nif_AlCoCrCuFe showing up to 88% Faradaic efficiency for NO2- and near 100% ...

But storing and transporting the gas pose technical challenges. With this in mind, Fraunhofer researchers use ammonia, a ...

Therefore, chemical hydrogen carriers have been identified as an alternative to the direct use of hydrogen. Transforming hydrogen into ammonia at the point of synthesis would reduce the pressure and ...

Researchers have developed a ligand-protected direct hydrogen reduction strategy to prepare zeolite-confined Pt-Pd bimetallic ...
