Spin effects in oxygen electrocatalysis: a discussion
(Elsevier Science, 2013-04)
The reduction of molecular oxygen in triplet and singlet spin states at metal electrodes is analyzed in the framework of quantum mechanical theory of charge transfer. Both outer- and inner-sphere mechanism is considered. ...
Electrocatalysis of oxygen reduction at electrodeposited molybdenum phosphate-based films
(Elsevier Science, 2012-04)
This work reports an electrode material containing molybdenum phosphate that shows a very interesting behavior as an electrocatalyst for the reduction of oxygen to water (ORR) in acid medium. The material is electrodeposited ...
Adsorption of 4,4′-Dithiodipyridine Axially Coordinated to Iron(II) Phthalocyanine on Au(111) as a New Strategy for Oxygen Reduction Electrocatalysis
(Wiley VCH Verlag, 2018-07)
The coordination of PySSPy to FePc was monitored by UV/Vis spectroscopy while the adsobed FePc, anchored by PyS−Au(111), was examined by in situ STM in 0.1 M HClO4 and X-ray photoelectron spectroscopy (XPS). Rotating-dis ...
Electrocatalysis on noble metal and noble metal alloys dispersed on high surface area carbon
(Ecole Polytechnique Montreal, 2003-01-01)
In this work, a simple route to prepare carbon supported Pt/C, Pt:Ru/C, Pt:Mo/C and Pt:Ru:Mo/C catalysts is reported. The electrochemical properties of the several carbon materials used as substrates in the absence and in ...
Oxygen Reduction Reaction at Penta-Coordinated Co Phthalocyanines
(Frontiers Media S.A., 2020-01)
From the early 60s, Co complexes, especially Co phthalocyanines (CoPc) have been extensively studied as electrocatalysts for the oxygen reduction reaction (ORR). Generally, they promote the 2-electron reduction of O2 to ...
Surface spectators and their role in relationships between activity and selectivity of the oxygen reduction reaction in acid environments
(2015-08-12)
Abstract We use the rotating ring disk (RRDE) method to study activity-selectivity relationships for the oxygen reduction reaction (ORR) on Pt(111) modified by various surface coverages of adsorbed CN<inf>ad</inf> ...
