The continuous growth of energy consumption,and the energy security and environmental protection issues caused by the burning of fossil fuels have become increasingly significant.Therefore,the study of alternative energy sources has attracted widespread attention.Hydrogen has the advantages of high energy density,no pollution,and abundant resources.It is considered to be one of the most potential alternatives to oil and natural gas.The most common method of hydrogen production is electrolysis of water.To achieve efficient hydrogen production,it is usually necessary to add catalysts(ruthenium and ruthenium-based materials)to improve the hydrogen evolution effect.This article reviews the preparation methods of ruthenium(Ru),the cheapest metal element among the platinum(Pt)group elements,and ruthenium-based materials as efficient electrocatalysts,and clarifies the hydrogen evolution promotion mechanism,hydrogen evolution effect,and stability.
