An amperometric ethanol sensor based on a Pd–Ni/SiNWs electrode

Ethanol sensor development based on ternary-doped metal oxides (CdO/ZnO/Yb2O3) nanosheets for environmental safety

“…The reactivity of ethanol was very high as compared to that of other chemical towards the surface under similar condition. [54][55][56] When ethanol reacts with the adsorbed oxygen on the exterior/interior of the layer, it oxidized to carbon dioxide and water, releasing free electrons (6e À ) in the conduction band, which could be expressed through the following reaction (x):…”

An electrochemical methanol sensor based on a Pd–Ni/SiNWs catalytic electrode

“…Peak a at −0.3 V is mainly attributed to the electrocatalytic oxidation reaction of methanol on the Pd. The oxidation reactions can be described as follows [26][27][28][29][30][31][32]18]:…”

“…Concurrently, plenty of active oxygen atoms become available at Pd free sites and organic species that are incompletely oxidized during the forward sweeping are removed. These give rise to oxidation peak c [30][31][32]. The mechanisms of peak b and c are of great importance to maintaining the stability of the Pd-Ni/SiNWs electrode.…”

Preparation, characterization and electrocatalytic activity for oxygen reduction reaction in PEMFCs of bimetallic PdNi nanoalloy

“…Bimetallic nanoalloys (BMNAs) formed by incorporation of transition metal with noble metal are found to be effective in the field of catalysis due to their unique role of controlling the activity, selectivity and stability as catalysts [1][2][3][4][5]. As a consequence of the bimetallic union, the electronic-structural modifications drastically influence the catalytic performance of the mixed-metal catalyst systems showing enhancement in specific properties at an optimum composition because of the synergistic effect of the composition [6][7][8][9]. Among various non-platinum cathode catalysts, palladium has attracted considerable attention due to its promising application potential as cathode electrocatalysts in proton exchange membrane fuel cells (PEMFCs) [10][11][12].…”
