The rational design of HER catalysts is fundamentally important for the promotion of hydrogen by water electrolysis. The heterostructured catalyst Ru/Ni 3 S 2 /NiFe LDH-NF is prepared by hydrothermal and electrodeposition methods. The catalyst shows impressive HER performance (−164 mV vs RHE@100 mA·cm –2 ). The interfacial interaction between the multiphases and the introduction of Ru active sites contributed to the improvement of the HER property. The assembled Ru/Ni 3 S 2 /NiFe LDH-NF||Ni 3 S 2 /NiFe LDH-NF for glycerol-assisted hydrogen production demands only 1.49 V to enable a current density of 100 mA·cm –2, with formate yield and selectivity as high as 90.4% and 94.1%, respectively. This work provides a highly dispersed metallic Ru deposite on Ni 3 S 2 /NiFe LDH-NF by electrodeposition to improve HER properties.
