As HER efficiency is influenced by several parameters, including overpotential, Tafel slope, and exchange current density. MXenes MBenes effectively optimize these parameters improving the adsorption desorption of hydrogen atoms, thus enhancing overall reaction kinetics. Density Functional Theory (DFT) studies have provided insight into how modifications at atomic level in lead to favorable energetics. The binding energies intermediates most active sites on material's surface can be estimated using DFT simulations which further helps screening different compositions, enabling identification promising candidates for experimental validation. For instance, shown that certain possess basal plane activity, a rare property allows entire 2D contribute process, increasing number performance.

Abstract Bulk molybdenum boride electrocatalysts have emerged as cost‐effective alternatives to platinum‐based catalysts toward the hydrogen evolution reaction (HER), particularly under harsh industrial conditions requiring high current densities. However, differences in electrode preparation methods between borides and Pt/C thus complicate direct activity comparison. In this study, vanadium‐stabilized monoboride (V 0.3 Mo 0.7 B) nanoparticles are synthesized shown outperform at industrially relevant densities same experimental conditions, achieving 1000 mA cm −2 with an overpotential of just 0.452 V compared 0.837 for Pt/C. Our density functional theory (DFT) calculations demonstrate that 0.31 0.69 B exhibits improved Gibbs free energy HER (ΔG H = ‐0.12 eV) coverages (80 100%), showcasing its superior catalytic Stability tests retains 97% performance after ≈28 h operation , positioning it a compelling candidate sustainable production.
