Tackling the Activity and Selectivity Challenges of Electrocatalysts toward the Nitrogen Reduction Reaction via Atomically Dispersed Biatom Catalysts
TL;DR: By means of large-scale density functional theory (DFT) computations, a descriptor-based design principle is reported to explore the large composition space of two-dimensional (2D) bi-atom catalysts (BACs) and identify three homonuclear and 28 heteronuclear BACs which could break the metal-based activity benchmark towards efficient NRR.
