Zur elektrokatalytischen Reduktion des NO₃ ^--Ions bei positiven Elektrodenpotentialen

Nitrogen Cycle Electrocatalysis

“…The reduction of nitrate on polycrystalline platinum at low nitrateconcentrationhasbeenthesubjectofmanystudies. 244,[289][290][291][292][293][294][295][296] Figure 23 shows the typical voltammetry of nitrate reduction on a polycrystalline platinum electrode in sulfuric and perchloric acid. 295 Under these conditions, we are probing the direct reduction pathway, which has significant overpotential on platinum.…”

Catalytic Reduction of Nitrate in Water on a Monometallic Pd/CeO2 Catalyst

“…The electrolytic reduction of nitrate anions has been under investigation for a long time (3)(4)(5)(6)(7)(8)(9) and constitutes an important part of the electrochemistry of nitrogen compounds. Chemical reduction of nitrate in water has also been studied (10,11) in presence of ferrous ions and a copper catalyst, or in presence of metallic iron as reducing agent.…”
