An electrochemical and XPS study of the electrodeposited binary Pd–Sn catalyst: The electroreduction of nitrate ions in acid medium

Catalytic oxidation of toluene over Pd/Co3AlO catalysts derived from hydrotalcite-like compounds: Effects of preparation methods

“…The Pd 3d in four catalysts exhibits almost the same doublet (i.e., 3d 5/2 and 3d 3/2 ) with a spin-orbit splitting, in agreement with the literature [28,29], of about 5.3 eV (Fig. 3A).…”

Efficient electrochemical reduction of nitrate to nitrogen on tin cathode at very high cathodic potentials

“…A fractional reaction order was reported previously by other workers on Pt-Pd-Ge [22], Pd-Sn-Au [30] and Cu-Tl [42] and it was explained assuming a Temkin adsorption [5,27]. Recently, Casella and Contursi [43] reported a value of 1.25 for the reaction order on Pd-Sn in acid medium.…”

Nitrogen-doped graphene supported highly dispersed palladium-lead nanoparticles for synergetic enhancement of ethanol electrooxidation in alkaline medium

“…3. Pd (0) generated from NaBH 4 reduction [47]. Pb 4f signal of PdPb/ NG consists of Pb (0) and (II) species as shown in Fig.…”

“…Some Pb atoms may be deposited on the metal particle surfaces or form particles without alloying with Pd, those Pb atoms could be readily oxidized by oxygen in air. These oxides could play a positive role in the electro-catalytic oxidation of small organic molecules [25,47]. On the other hand, the stronger Pb (0) peaks represented more Pb was alloyed with Pd, which caused the slight change in lattice parameter of the catalyst as exhibited in XRD patterns.…”
