A Review of the Application of Heterostructure Catalysts in Hydrogen Evolution Reaction

Abstract Hydrogen energy as a significant part of clean energy in the future has been widely studied. Hydrogen production from electric cracking water is the most effective and mature development method at present. Heterostructured electrocatalysts are favored due to their low overpotential, excellent assembly structure and good electron transfer ability. Consequently this paper reviews the development of heterogeneous electrocatalysts, the measurement parameters of electrocatalytic hydrogen evolution reaction (HER), and related research progress, and gives the hydrogen evolution mechanism in acidic, alkaline and neutral environments. Finally, we explain the essential development direction and severe challenges in this field.
