Dual-modulation of electronic structure and active sites of PtCu nanodendrites by surface nitridation to achieve efficient methanol electrooxidation and oxygen reduction reaction

A facile method to prepare PtCu nanodendrites rich in multiple active sites was reported using pyridine as a surface modifier. They exhibit outstanding electrocatalytic performance towards oxygen reduction reaction and methanol electrooxidation in acidic medium. A facile method to prepare PtCu nanodendrites rich in multiple active sites was reported using pyridine as a surface modifier. They exhibit outstanding electrocatalytic performance towards ORR and MOR in acidic medium.
