The electrochemical ethanol oxidation reaction(EOR)plays a crucial role in electrochemical hydrogen production and direct ethanol fuel cells,both vital for utilizing renewable energies.Ni-based catalysts are pivotal in enabling efficient EOR,leading to the formation of acetic acid/acetaldehyde or CO2.These can serve as alternative anodic oxidation reactions for oxygen evolution reaction(OER)in water electrol-ysis or the anodic reaction for direct ethanol fuel cells,respectively.This review explores recent advance-ments in EOR over Ni-based catalysts.It begins with an overview of EOR performance across various Ni-based catalysts,followed by an examination of the reaction chemistry,mechanism,and active sites.The review then delves into strategies for designing highly active Ni-based EOR catalysts.These strategies include promotion with transition metals,noble metals,nonmetals,and carbon materials,as well as cre-ating amorphous structures,special morphologies,and single-atom catalysts.Additionally,it discusses the concept of self-supporting catalysts using three-dimensional porous substrates.Finally,the review highlights emerging methodologies that warrant further exploration,along with future directions for designing highly active and stable EOR catalysts.
