Electrochemical reduction of NOx species at the interface of nanostructured Pd and PdCu catalysts in alkaline conditions

[Display omitted] •The synthetized nanoparticles have an average size of 12 nm (Pd) and 3 nm (PdCu).•The incorporation of copper improves the NOx electro-reduction process.•The PdCu/C catalyst exhibit the best electroreduction performance for all solutions.•Catalysts with a low noble metal amount wa...
