Two dimensional LiMgAs: A topological quantum catalyst for hydrogen evolution reaction

Quantum materials such as Topological Insulators (TI) have been promising due to diverse applications of their robust surface/edge states in the bulk (3D) and two-dimensional (2D) regime. Such conducting surface 3D systems, host "\textit{electron bath}" which are known facilitate catalysis. However, analogous effects 2D scenarios wherein, helical edge giving rise Fermionic accumulation has scarcely addressed. Using density functional theory based \textit{first-principles} calculations, we demonstrate that, TI LiMgAs can be exploited excellent catalytic response towards Hydrogen evolution reactions. The Gibbs free energy cases was found low $-$0.02 eV is quite superior compared other reported literature. concept presented herein extended well used realise novel topological quantum catalysts for ultra-high performance efficient applications.
