Hydrogen electrocatalysis factors

Moreover, the conductivity, and hence the catalytic decomposition of hydrogen peroxide, has been observed to influence the stability of the oxygen electrode. The stability of phthalocyanine catalysts is a decisive factor for the practical applicability of organic catalysts in fuel cells operating in an acid medium. This is therefore a very important observation. The observed disturbance of the delocalization of the n electrons (rubiconjugation) in Fe-polyphthalocyanines, in addition to the correlation between conductivity on the one hand, and electrocatalysis and catalytic decomposition of hydrogen peroxide on the other, leads to a special model of the electroreduction of oxygen on phthalocyanines. The model... 

Fast progress of platinum computational elctrochemistry is stimulated by electrocatalysis, and tlte studies of CO adsorption predominate. Accumulated experience is extremely useful for modeling the reversible adsorption at the interface, but today the latter looks like a tiny brook in the vicinity of computational mainstream. The closest layer going from electrocatalysis is theoretical/ computational prediction of electrocatalytic activity in hydrogen reactions, °° as it requires the modeling of hydrogen adatoms. The main problem in this case is comparison with experiment, because a lot of factors besides adlayer stmcture affect the observed reaction rates. 

Research in electrocatalysis was strongly stimulated in the early 1960s by efforts toward the development of various types of fuel cells. Studies were initiated on the various factors influencing the rates not only of hydrogen evolution but also of other reactions, particularly cathodic oxygen reduction and the complete oxidation of simple organic substances ( fuels ) to carbon dioxide. The...
