This brief review reports the recent advancement of metallic glasses and metallic glass nanostructures for functional electrocatalytic applications.Metallic glasses(MGs)or amorphous metals result from quench-ing the melts at a high cooling rate(e.g.,106 K/s)),bypassing crystallization.Metallic glasses are devoid of long-range translational order,no defects like grain boundaries,and multiple elements included.Due to these unique structural features,MG's show distinct and valuable mechanical,physical and chemi-cal properties and therefore were widely studied as a structural material for decades.Even though MGs were proposed for catalytic applications earlier,a comprehensive study or attempt to apply these ma-terials successfully in electrocatalytic applications are few since the intrinsic surface area is compara-bly lesser.A rejuvenated interest among the research community for applying various novel strategies in catalytic applications of MGs is highlighted in the present review.Theoretical approaches using den-sity functional theory(DFT)and high-throughput screening assisted with machine learning paradigm ad-vances the discovery of new MGs,which demonstrated high potential for catalytic applications.We focus on the basic features and recent advances in the MGs for catalytic applications like electrocatalytic water splitting reactions like HER,OER,fuel cell reactions like ORR,alcohol oxidation reactions like MOR,EOR,and degradation of harmful organic dyes from the industrial effluents.The presently advancing strate-gies for enhancing the performance of these metallic glass electrocatalysts through nanostructuring and high-throughput screening are discussed.The unique atomic-scale structural mechanism of the metallic glasses,which can favor the development of high-performance electrocatalysts even comparable to cur-rently available precious-metal-based catalysts,will be discussed.Finally,we also give future directions on designing novel and superior metallic glass-based advanced catalysts.
