Abstract:

Alkaline electrochemical water splitting has the characteristics of easy operation and low cost,which is the most widely used technology to convert renewable resources to hydrogen energy.However,electrolytic water has the problem of high energy consumption,so highly efficient catalysts are needed to improve the energy conversion efficiency.Ruthenium possessed similar bond strength with hydrogen,has attracted increasing attention as promising electrocatalyst for hydrogen evolution.The latest research progress in the preparation of ruthenium-based catalysts and the application in hydrogen evolution reaction from alkaline water electrolysis were reviewed.Compared with cheap transition metal materials,ruthenium-based catalyst had excellent electrochemical activity and stability,which was promising hydrogen evolution material.The ruthenium metal and its alloys,ruthenium based phosphides,ruthenium based sulfides and ruthenium based selenides mainly studied at present,were briefly introduced and evaluated respectively.Finally,the existing problems and future development direction of ruthenium based electrocatalysts in hydrogen production were put forward.

Key words: ruthenium-based catalysts, alkaline water electrolysis, hydrogen evolution reaction, electrocatalyst
