Controlled potential coulometric analysis of palladium alloy

Palladium monolayer and palladium alloy electrocatalysts for oxygen reduction.

We investigated the oxygen-reduction reaction (ORR) on Pd monolayers on various surfaces and on Pd alloys to obtain a substitute for Pt and to elucidate the origin of their activity. The activity of Pd monolayers supported on Ru(0001), Rh(111), Ir(111), Pt(111), and Au(111) increased in the following order: Pd/Ru(0001) < Pd/Ir(111) < Pd/Rh(111) < Pd/Au(111) < Pd/Pt(111). Their activity was corr...

Electroanalysis and Coulometric Analysis

Electroanalysis and Coulometric Analysis

Several new books and journals containing material of electroanalytical and electrochemical interest have appeared. The newest edition of “Standard Methods of Chemical Analysis” (329) includes chapters discussing the fundamentals of electrogravimetric and coulometric methods. Zozulya has written a brief monograph on coulometric analysis (341) and coulometric titrations in nonaqueous solvents ha...

Rapid Synthesis of Rhodium–Palladium Alloy Nanocatalysts

Noble metals are widely used as catalysts in a variety of key industrial processes. In particular, rhodium is used to catalyze the reduction of NOx to N2 and O2 in exhaust gas abatement and is also used in the conversion of bulk hydrocarbon feedstocks and syngas into more highly oxygenated hydrocarbons (e.g. , hydroformylation). 2] Palladium also plays a myriad of critical roles, including CO-t...

Development of Palladium-Alloy Membranes for Hydrogen Separation and Purification

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...
