چکیده
Abstract The electrocatalytic nitrogen oxidation reaction (NOR) to generate nitrate is gaining increasing attention as an alternative approach the conventional industrial manufacture. But, current progress in NOR limited by difficulties activation and conversion of strong N≡N bond (941 kJ mol −1 ). Herein, we designed utilize sulfate enhance performance over Rh electrocatalyst. After addition sulfate, inert nanoparticles exhibited superior with a yield 168.0 μmol g cat h . 15 N isotope‐labeling experiment confirmed produced from electrooxidation. A series electrochemical situ characterizations theoretical calculation unveiled that promoted adsorption decreased energy barrier, formed radicals reduced potential‐determining step, thus accelerating NOR.

Cobalt/copper-decorated carbon nanofibers as novel non-precious electrocatalyst for methanol electrooxidation
In this study, Co/Cu-decorated carbon nanofibers are introduced as novel electrocatalyst for methanol oxidation. The introduced nanofibers have been prepared based on graphitization of poly(vinyl alcohol) which has high carbon content compared to many polymer precursors for carbon nanofiber synthesis. Typically, calcination in argon atmosphere of electrospun nanofibers composed of cobalt acetat...
متن کاملNi@Pt core-shell nanoparticles as an improved electrocatalyst for ethanol electrooxidation in alkaline media
Core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. In this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of Pt thin layer as the shell and Ni nanoparticles as the cores. The described method herein is suitable for large-scale and low-cos...
متن کاملA rhodium/silicon co-electrocatalyst design concept to surpass platinum hydrogen evolution activity at high overpotentials
Currently, platinum-based electrocatalysts show the best performance for hydrogen evolution. All hydrogen evolution reaction catalysts should however obey Sabatier's principle, that is, the adsorption energy of hydrogen to the catalyst surface should be neither too high nor too low to balance between hydrogen adsorption and desorption. To overcome the limitation of this principle, here we choos...
متن کاملRhodium-catalyzed sequential allylic amination and olefin hydroacylation reactions: enantioselective synthesis of seven-membered nitrogen heterocycles.
Dynamic kinetic asymmetric amination of branched allylic acetimidates has been applied to the synthesis of 2-alkyl-dihydrobenzoazepin-5-ones. These seven-membered-ring aza ketones are prepared in good yield with high enantiomeric excess by rhodium-catalyzed allylic substitution with 2-amino aryl aldehydes followed by intramolecular olefin hydroacylation of the resulting alkenals. This two-step ...
