文摘
- •
Adsorbed phosphomolybdates enhance catalytic activity of PtRu nanoparticles.
- •
Increase in ethanol oxidation current is correlated to faster dehydrogenation.
- •
Phosphomolybdates adsorbed on PtRu cause reduction of Ru surface oxides.
- •
VB eDOS increase is responsible for increased kinetic of ethanol dehydrogenation.
