Kinetic study of nitrate reduction on Pt(1 1 0) electrode in perchloric acid solution

Redox transformations of adsorbed NO molecules on a Pt(100) electrode

“…Attention to these processes does not wane due to its fundamental and applied importance. As the reduction of nitrogen-containing compounds is a structure-sensitive process, the investigations performed at single crystal electrodes are of greatest interest [1][2][3][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. The use of the electrodes with clearly characterized surface structure allows revealing the correlations between electrochemical activity of adsorption sites and their structure.…”

Investigation of nitrate reduction on polycrystalline Pt nanoparticles with controlled crystal plane

“…The nitrate reduction on Pt electrode has been studied for several decades and constituted an important part of the electrochemistry of nitrogen compounds [2,[5][6][7][18][19][20][21][22][23]. Nart et al investigated reduction of NO 3 − on polycrystalline Pt bulk by in situ FTIR, suggesting that the initial potential of nitrate reduction is 0.8 V (Pd|H 2 ) with generation of adsorbed NO [2].…”

“…Nevertheless, the morphological effect of polycrystalline platinum on nitrate reduction was seldom studied. In order to investigate the dependence of activity on different Pt plane, a series of researches have also been carried out on Pt single crystal electrode [19][20][21][22][23]. It is suggested that…”

Cu UPD at Pt(100) and stepped faces Pt(610), Pt(410) of platinum single crystal electrodes

“…Consequently, there is a possibility to establish a correlation between the structure of adsorption sites and their catalytic activity [17][18][19][20][21][22][23][24][25][26][27][28][29]. Our previous studies of nitrate reduction on Pt(111) and Pt(111) + Cu electrodes [22] have shown that sulfate anions block the adsorption sites on the surface of the modified electrode, thus hindering the adsorption of nitrate anions and their reduction.…”
