Abstract: Hydrogen energy is considered to be one of the clean energy sources most likely to alternate fossil fuels. The exploration of catalytic materials suitable for electrocatalytic water splitting to produce hydrogen has become an important subject in the field of water electrolysis. Limited to the phenomena of easy stacking of nano-powder materials and poor conductivity during the catalytic reaction, the combination of nano-active materials and conductive substrates to construct three-dimensional (3D) array electrodes with open porous structures has become a research hotspot. This article first summarizes the advantages of 3D array electrodes for water electrolysis, then briefly describes several strategies for improving the catalytic performance of materials, and finally classifies and summarizes the array catalytic materials used for water electrolysis. It is expected to provide reference for the design and synthesis of electrocatalytic materials in the future.

Key words: electrocatalytic water splitting, hydrogen energy, 3D array electrode
