Abstract
The reaction mechanisms of oxygen reduction of platinum in alkaline medium are determined once a set of reacting species and elementary reactions is specified. The technique utilized to generate all the possible reaction mechanisms is based upon the principles of combinatorial analysis and linear algebra along with application of the principle of microscopic reversibility. The development of this method by Happel and Sellers has enabled them to study complex mechanisms for some important industrial reactions in heterogeneous catalysis. A preliminary evaluation analysis of the myriad reaction mechanisms for oxygen reduction is accomplished by invoking the concept of a stoichiometric number and a corresponding rate‐determining elementary reaction. The number of mechanisms which are consistent with a given experimentally derived stoichiometric number is considerably less. The resulting set of mechanisms forms an important basis for further investigations.
