Electrochemistry of Cd₃As₂—A 3D Analogue of Graphene

Abstract Graphene has been well‐known for its outstanding electrochemical properties over the years owing to its zero band gap and structural advantages. Lately, Cd₃As_2, a three‐dimensional (3D) Dirac semi‐metal, has been fervently explored in the field of material physics due to its high electron carrier mobility and transport properties. However, unlike graphene and its derivatives, the electrochemical behavior of Cd₃As₂ has been underexplored despite it being established as a bulk analogue of 3D graphene in its electronic properties. In this work, we investigate the interesting electrochemistry of Cd₃As₂ in terms of its heterogeneous electron transfer, as well as its electrocatalytic potential in energy applications like hydrogen evolution reaction.
