摘要：
A facile method was proposed to prepare mesoporous AgPtPd nanotubes (M-AgPtPd NTs) alloy electrocatalysts. The M-AgPtPd NTs presented excellent electrocatalytic activity and robust durability for H-2 evolution in 1.0 M KOH solutions. Specifically, the M-AgPtPd NTs achieved a significantly lower overpotential (19.6 mV) at the current density of 10 mA.cm(-2) compared with commercial Pt/C catalysts (31.6 mV). The M-AgPtPd NTs also displayed remarkable stability after 1000 cycles. This excellent catalytic activity of the M-AgPtPd NTs electrocatalysts can be ascribed to the trimetallic characteristics and the unique mesoporous structure. (C) 2020 Elsevier B.V.
