Hydrogen evolution of a MoS 2 /AOCF electrocatalyst doped with Ni element
Efficiency and stability are the key factors of MoS 2 electrocatalysts. Herein, a MoS 2 complex (Ni@MoS 2 /AOCF) was successfully prepared by amidoximized polyacrylonitrile (AOCF) coordination and Ni doping. Impressively, the as-synthesized Ni@MoS 2 /AOCF electrocatalyst exhibited satisfying hydroge...

electrocatalysts. Herein, a MoS
2
complex (Ni@MoS
2
/AOCF) was successfully prepared by amidoximized polyacrylonitrile (AOCF) coordination and Ni doping. Impressively, the as-synthesized Ni@MoS
2
/AOCF electrocatalyst exhibited satisfying hydrogen evolution reaction (HER) performance with a low onset potential (116 mV) and small Tafel slope (54.8 mV dec
−1
). The structure and performance characterizations indicate that MoS
2
grow epitaxially on AOCF
via
coordination bonds formed between Mo and –OH and –NH
2
of AOCF, and the strong bonding effect endows MoS
2
/AOCF with numerous active sites and excellent stability. Besides, the conductivity of MoS
2
/AOCF is obviously improved by Ni element doping and finally results in superior HER performance in acidic solutions. |
