- •
Ptn0Au composites (n = 1÷3) were obtained by the successive displacement of three MLCuad in the PtCl42 − solution.
- •
The displacement of MLCuad proceeded to afford Pt clusters rather than layer-by-layer.
- •
Pt10Au – Pt20Au – Pt30Au – pc Pt, the specific surface activity of Pt increased as regards MOR and decreased as regards FAOR.
- •
The possible reasons for the different behavior of Ptn0Au activity with the increase in n in FAOR and MOR are discussed.
- •
Composites Ptn0Au demonstrated the high degree of Pt utilization not only in FAOR but also in MOR.
