Electrocatalytic reduction of NO3- in a neutral solution on an electrodeposited film of amorphous Pd33Ni60P7 alloy

摘要: Abstract An amorphous Pd33Ni60P7 alloy was prepared by electrodeposition in a bath containing 0.02 mol L−1 PdCl2, 0.04 mol L−1 NiSO4 · 6H2O, 0.24 mol L−1 H3PO3, 0.32 mol L−1 H3BO3, and 0.08 mol L−1 ethylenediamine (C2H8N2), under conditions of pH 4.0, 50 °C 25 mA cm−2. The structure the deposit confirmed with X-ray diffraction (XRD) analysis. activity electrocatalytic reduction nitrate on studied cyclic voltammetric (CV) technique neutral 0.1 mol L−1 KClO4 solution or without KNO3. results indicate that exhibits higher for comparison electrodeposited films Pd, Ni Pd–Ni, which could be owing to its structure. reaction NO 3 - electrode is totally irreversible process.
