Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

Advanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

Simulation of Ammonia Synthesis [PDF]

American Journal of Chemical Engineering, 2013
Ammonia is prodeuced to give a final product named urea which is a very important fertilizer for higher nitrogen content.Several processes has been invented for optimum production of ammonia. Now-a-days, Ammonia production is mainly done by Haber process in which nitrogen andhydrogen react in the presence of an iron catalyst to form ammonia.
