Electrochemical denitrification is a promising technology for removing NOx species due to its environmental impact. In this work, nanostructured palladium electrocatalysts (3.2-3.7 nm) stabilized with different compounds namely lignin, oleylamine, octylamine, and 2-methyl-2butanol supported on Vulcan carbon were synthesized from organometallic prec...

In this work, the cell potential during an electrochemical reaction in a separate compartment with anionic-membrane designed for electro-leaching of electronic-waste (E-waste) was studied. For such an approach, in the anode-side the electro-leaching of metals and the oxygen evolution reaction (OER) were monitored using a titanium plate in a HNO3 so...

The electrocatalytic reduction of CO2 (CO2RR) on carbon-supported palladium-based (Pd/C, Pd-Cu2O/C, Pd-SnO2/C) and non-precious metal oxides (Cu2O/C and SnOX/C) was investigated through physicochemical and electrochemical measurements. The formation of a solid solution in the bimetallic Pd-based compounds was confirmed by a contraction of the Pd un...

It is accepted that the mechanism of electro-generated active chlorine (i.e. chloride oxidation on DSAs) involves water oxidation and hydroxyl radical co-electrosorption to initially form HOCl ads on the anode surface in a single pathway, and subsequent production of Cl 2 and OCl − ions. The present study comprehensively evaluates the chloride oxid...

Electrochemical reduction of NOx species such as nitrates (NO3−), nitrites (NO2−), nitric oxide (NO), nitrogen dioxide (NO2) and their mixtures, was studied at the interface of palladium (Pd) and palladium-copper (PdCu) nanoparticles supported on carbon Vulcan (C). The electro-catalysts were synthesized by impregnation route with a low noble metal...
