AB - The current state of knowledge for the electrooxidation of ammonia on Pt electrodes with well-defined surfaces is discussed. From seminal studies on single crystal electrodes in alkaline media, the reaction is known to be highly dependent upon the surface structure. Pt surfaces with (100) orientation are the most active, while surfaces with (111) and (110) orientation have greatly reduced reactivity. Wide terraces of (100) orientation are also found to be significantly more active than (100) step domains. We describe NH3 electrooxidation on cubic nanoparticles enclosed with six facets of (100) atoms and highlight convenient methods which produce Pt catalysts with sufficiently tuned (100) surface structure such as epitaxial growth of Pt thin layers and Pt electrodeposition; both methods offer a low cost alternative to proxy the synthesis of single crystal (100) Pt catalysts. Emerging, bimetallic catalysts are anticipated to shed light on the ammonia oxidation reaction mechanism and further improve the reaction by reducing self-poisoning of the reaction.
