The adsorption of BiIII on PtNPs was confirmed by electrochemical studies. Without PtNPs, BiIII did not adsorb directly on the surface of glassy carbon electrode. The specific chemistry resulted in high electrocatalysis performance of the obtained nanocomposites toward glucose oxidation compared with PtNPs alone because of the dual effects of Bi(III). On the one hand, Bi tends to bind OH− from alkaline solution and then to share it with the adjacent Pt atom. This binding leads to an increase in number of hydroxylated Pt centers, which are the active species for the electrochemical oxidation of glucose. On the other hand, Bi acts as a binder to cross-link PtNPs and to immobilize them on the surface of glassy carbon electrode. The fabricated BiIII/PtNP nanocomposites may have the potential applications in the areas of electrocatalysis or electroanalysis.
