Research Progress of Noble Metal Electrocatalysts for Acidic Oxygen Evolution Reaction
摘要
Abstract
Hydrogen production by water electrolysis is a clean production technology.Compared with alkaline water electrolysis(AWE),proton exchange membrane water electrolysis(PEMWE)has the advantages of chemical stability,high proton conductivity,and non-porous gas isolation.However,the oxygen extraction reaction(OER)has a harsh acidic environment and involves a four-elec-tron-transfer step with a slow kinetic process,which requires highly active,acid-resistant and corrosion-resistant electrocatalyst materi-als.Noble metal materials play a crucial role as high-performance acidic OER electrocatalysts due to their high activity and good selec-tivity.So far,several catalysts composed of Ir-based and Ru-based materials have been designed and applied to acidic OER.This pa-per reviews the research progress of noble metal materials electrocatalysts for acidic OER in recent years.Firstly,two mainstream OER mechanisms,namely,adsorbate evolution mechanism and lattice oxygen oxidation mechanism,are described,and then the recently re-ported acidic OER electrocatalysts are summarized in terms of Ir-based and Ru-based noble metal materials.Finally,the development direction of noble metal catalysts in the acidic oxygen-oxidation reaction,such as reaction mechanism and structural design,is anticipa-ted.关键词
