Interfacial Electronic Modulation of Dual-Monodispersed Pt-Ni₃S₂ as Efficacious Bi-Functional Electrocatalysts for Concurrent H₂ Evolution and Methanol Selective Oxidation.

ABSTRACT: Constructing the efficacious and applicable bi-functional electrocatalysts and establishing out the mechanisms of organic electro-oxidation by replacing anodic oxygen evolution reaction (OER) are critical to the development of electrochemically-driven technologies for efficient hydrogen production and avoid CO₂ emission. Herein, the hetero-nanocrystals between monodispersed Pt (~ 2 nm) and Ni₃S₂ (~ 9.6 nm) are constructed as active electrocatalysts through interfacial electronic modulation, which exhibit superior bi-functional activities for methanol selective oxidation and H₂ generation. The experimental and theoretical studies reveal that the asymmetrical charge distribution at Pt-Ni₃S₂ could be modulated by the electronic
