Dopant-induced metal support interactions

In dispersed metal-support systems (Fig. 11.2 right), one can vary pe(M) - M-e(S) by varying the support or by doping the support with aliovalent cations. This is known in the literature as dopant-induced metal-support interactions (DIMSI).8,11,41,42 Thus one can again vary the electrochemical potential and thus the coverage of backspillover O2 on the supported catalyst surface. 

The effect of dopant-induced-metal-support interactions (DIMSI) studied for years by Verykios and co-workers [97]. 

The use of solid electrolytes as active catalyst supports to induce the effect of Non-Faradaic Electrochemical Modification of Catalytic Activity (NEMCA) [16] or in situ controlled promotion [17] and alter the catalytic properties of metal catalysts has been described in detail previously [16-18]. A goal of the present work was to explore the possible relationship between the NEMCA effect [16-18] and the effect of dopant-induced-metal-support interactions [6,7,9,10].
