Aiming to design efficient,inexpensive,and durable electrocatalyst for hydrogen production via catalytic cracking of water,Ni3S2 nanowire@NiCo-LDH nanocomposite(Ni3S2@NiCo-LDH)is synthesized.The results show that the prepared composite has a large number of active sites and exhibits excellent electrocatalytic hydrogen production performance.Ni3S2@NiCo-LDH electrode material achieves a current density of 10 mA·cm-2 at only 1.373 V in a KOH electrolyte containing urea.In Ni3S2@NiCo-LDH//Pt,a two-electrode system,the voltage is only 1.463 V at a current density of 10 mA·cm-2.It is verified that Ni3S2@NiCo-LDH nanocomposite is an excellent new catalytic hydrolysis hydrogen production electrocatalyst.
