Effect of chemical corrosion and alloying on the catalytic activity of 18 carat gold for the electro-oxidation of HCOOH

Role of composition and texture on bifunctional catalytic performance of extruded Au–Cu alloys

“…In fact, the alloying can tune the electronic structure of Au based catalysts, which plays a key role in catalytic activity. 46,47 As shown in Fig. 11 and S7,† the XPS spectra of Au 2 Cu and Au sample surfaces before and after the appearance of peak P 3 on CV curves tested in 0.5 M KOH + 0.5 M CH 3 OH solution were obtained.…”
