A facile approach to synthesize a Pt-doped metal-organic framework-derived layered double hydroxide with highly dispersed 2D nanosheets and excellent catalytic properties has been developed. This material shows low overpotentials and small Tafel slopes, making it a promising HER electrocatalyst in alkaline and neutral electrolytes.
A facile approach to synthesize a Pt-doped metal-organic framework (MOF)-derived layered double hydroxide (LDH), denoted as Pt@CuFe-LDHm, is developed. It consists of highly dispersed 2D nanosheets, and the excellent properties (high specific surface area and large porosity) inherited from CuFe(dobpdc) bestow it with superior catalytic properties. Pt@CuFe-LDHm shows low overpotentials of 33, 47 and 120 mV at 10 mA cm(-2) with small Tafel slopes of 34.0, 50.2 and 85.6 mV dec(-1) in 1.0 M KOH, 0.1 M KOH and 1.0 M PBS. This work paves the way for high-performance and durable HER electrocatalysts in alkaline and neutral electrolytes.
