In order to investigate the catalytic performance of V-doped Co

4

N in electrolyzed water

the Co/V-containing layered double hydroxide precursor of CoV-LDH was synthesized by a one-step hydrothermal method

then urea served as the nitrogen source to promote CoV-LDH phase transition to its nitride structure through chemical vapor deposition. As result

the vanadium-doped cobalt nitride V-Co

4

N was obtained. The structure appears as a two-dimensional nanosheet array structure which supported by three-dimensional nickel foam. T

he electrochemical method was used to study the catalytic properties of V-Co

N in electrolyzed water. The target structure shown bifunctional electrolytic water catalytic properties. When to drive the current density of 10 m A/cm

2

the required overpotential of the cathode and anode sections were 61 m V and 245 m V

respectively. Compared to that of commercial catalysts

it has a strong competitive advantage. Furthermore

the influence of the introduction of Mo、 Mn and Cr with different metal doping

different heat treatment temperatures and different anion coordination factors on the electrocatalytic activity of the target structure were also further studied. The results shown that the V doping

N as the coordination

and the heat treatment temperature of 350 ℃ were the proper choices to adjust the best catalytic activity and economic effect.
