Abstract:
The Haber-Bosch process using Fe-based catalysts is still the predominant technique for ammonia production despite tough reaction conditions and high energy consumption. In the present work, we have investigated iron adatom on the (110) surface of pure iron catalyst towards the electrocatalytic N2 reduction reaction (NRR) activity using density function theory (DFT) calculations. We demonstrate that the presence of adatom over the iron catalyst favours the NRR via alternating associative mechanistic pathway through a barrierless rate determining step (*NNH formation). Besides, the adatom-based catalyst requires lower working potential than the previously reported Fe(110) surface and Fe-nanocluster based catalysts. These findings may open a scope in terms of scrutinizing the atomicity effects over catalyst surface for various catalytic reactions.

Electron Carriers
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
