Abstract

Catalytic activity and cycle stability are the critical factors in improving the performance of the hydrogen evolution reaction (HER) of Ni

electrocatalyst. In this study

/amine oxime polyacrylonitrile polymer (AOCF) composites were successfully prepared from nickel chloride

thiourea

L-cysteine

and AOCF by solvothermal and ligand loading methods. The results of structure and performance characterization show that Ni

forms a coordination bond between Ni and —OH and —NH

on the AOCF chain

resulting in Ni

/AOCF composites. As HER electrocatalysts in acidic media

/AOCF composites exhibit excellent electrocatalytic activity and good cycle stability

with an overpotential of -233 mV

a Tafel slope of 94.7 mV/dec

and cycling stability of up to 50 h at a current density of -30 mV/cm

. As a result

/AOCF composites show the characteristics of high hydrogen evolution performance

low cost

and good stability.
