Preparation of Bimetallic Catalysts by Direct Redox Reaction 

In this case, metal-metal interactions result from surface redox reactions between the prereduced parent metal M and the oxidized form of the modifier The half reaction corresponding to the oxidation of the parent metal is the following  

According to the Nernst equation, the equilibrium potential (E z+p ) of the reversible oxidation of M is expressed as the following  

In the same way, the equilibrium potential of the reversible reduction of the modifier in oxidized form is given by  

If the value of the change in Gibbs free energy A(AG) given by
