Catalytic Rates and Activation Energies on Catalyst Work Function

Dependence of Catalytic Rates and Activation Energies on Catalyst Work Function e0 

A general observation that has emerged from in situ controlled promotion studies is that over wide ranges of catalyst work function 

Typical examples of electrophobic reactions are shown in Fig. 21 for the catalytic oxidation of C2H4 and of CH4 on PtA SZ. As shown in this figure, increasing e P also causes a linear variation in activation energy E  

This linear decrease in E with A(e0), which, for these systems, is due to the weakening of the Pt=0 bond strength with increasing is
