Oscillographic study of a palladium anode during electrochemical evolution of oxygen

Oscillographic study of a palladium anode during electrochemical evolution of oxygen. Gorodetskii, Yu. S.; Chesalov, Yu. F. (USSR). Reaktsionnosposobn. Koord. Polim. Soedin.Some commonly used reagents like 12036-04-3 and 7440-05-3 are used in this experiment., 123-7. Edited by: Polotebnova, I. A. Shtiintsa: Kishinev, USSR. (Russian) 1982. CODEN: 51HGAN. DOCUMENT TYPE: Conference CA Section: 72 (Electrochemistry) The oxidn. was studied of a Pd anode during electrochem. evolution of O in 0.1, 1.0, and 10N KOH by the oscillog. method at 20, 40 and 60° and anodic c.d. values of 1-40 A/dm2 and polarization time of 0.12-60 min. The total discharge curve for a Pd anode in alk. solns. consists of 5 sections. The lower oxide PdO is significantly more stable than the higher oxidePdO2. The stability of both oxides increases with increase of KOH concn., which agrees with the literature data. .

Effects of internal oxidation on the hydrogen permeation in Pd0

Effects of internal oxidation on the hydrogen permeation in Pd0.97Al0.03 and (Pd0.9Pt0.1)0.97Al0.03 alloys. Azambuja, V. M.; dos Santos, D. S.; Pontonnier, L.; Miraglia, S.; Fruchart, D. (Pemm-Coppe/UFRJ, Rio de Janeiro 21945-970, Brazil). Journal of Alloys and Compounds, 346(1-2), 142-146 (English) 2002 Elsevier Science B.V. CODEN: JALCEU. ISSN: 0925-8388. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) Specimens of the Pd0.97Al0.03 and (Pd0.9Pt0.1)0.97Al0.03 alloys, internally oxidized at 1073 K for 72 h, were submitted to three sorption-desorption cycles at 313 K by an electrochem. hydrogen permeation technique. The effects of internal oxidn. were investigated by X-ray diffraction (XRD) and TEM. We obsd. by XRD the formation of PdO2 only in the case of the Pd0.97Al0.03 alloy, while for the (Pd0.9Pt0.1)0.97Al0.03 alloy, there was no indication of internal oxidn. of the alloying elements after annealing at 1073 K for 72 h. TEM anal. in the heat treated Pd0.97Al0.03 alloy showed dispersed nanoppts. of Al2O3, markedly in coherent interface with the Pd matrix. However, in the heat treated (Pd0.9Pt0.1)0.97Al0.03 alloy, areas rich in Pt and Al were obsd. only, suggesting the formation of PtAl clusters. In the Pd0.97Al0.03 alloy due to the presence of Al2O3 and PdO2 the hydrogen diffusivity (Dapp=2.3′10-12 m2 s-1) is very low in comparison to that of the (Pd0.9Pt0.1)0.97Al0.03 alloy (Dapp=1.0′10-11 m2 s-1) and a heat treated pure Pd specimen (Dapp=5. 1333-74-0 and 12036-04-3 which are cas registry numbers of substances are two of reagents here.5′10-11 m2 s-1). The hydrogen soly. in the heat-treated Pd0.97Al0.03 is quite high (1075 mol H m-3) due to the appearance of new interfaces to trap hydrogen. The low value of hydrogen soly. presented by (Pd0.9Pt0.1)0.97Al0.03 (136 mol H m-3) is attributed to the non oxidn. of the constituting elements. .
