The Reaction between Hydrogen Peroxide and Cupric Ions

The Reaction between Hydrogen Peroxide and Cupric Ions 

According to Haber and Weiss (3b) the mechanism of the action of cupric ions corresponds closely to that of ferric ions so that instead of, for example, eqs. (5), (6), and (7), one has  

The promoting effect of cupric ions in decomposing hydrogen peroxide by ferric ions (19) was considered by Haber and Weiss (3b) to be mainly due to the reaction  

Recent work of Baxendale et al. (6) has confirmed these views. 

The catalytic decomposition of hydrogen peroxide on solid and colloidally dispersed metals has been studied particularly by Bredig et al. (20). These reactions have been treated by Weiss (21) from the point of view of the radical mechanism. On the basis of the electron theory the metal can be considered both as a source and as a sink of electrons. In conformity with the electron transfer processes outlined above, the reactions at the surface of the metal catalyst can be considered to be represented by processes of the type
