Abstract: Non-noble electrocatalysts for green hydrogen production and bifunctional water decomposition proficiencies are the focal topics for eco-friendly energy generation. Here, nanosheets of transition metal boride (Fe2B) decorated over 2D MXene (Ti3C2Tx) nanosheets embedded on 3D Nickel foam (NF) have emerged as a capable candidate showcasing industrial-scale current density in concentrated alkaline media. The Fe2B/MXene@NF catalysts demonstrate the superior bi-functional catalytic performance for simultaneous production of H2 and O2, achieving a current density of 100 mA cm⁻2 at a cell voltage of 2.04 V, 1.88 V, and 1.86 V in 1M, 3M, and 6M KOH electrolytes, respectively. The Fe2B/MXene catalysts exhibit excellent stability for industrial scale current density of 300 mA cm−2 for ∼80 h, suggesting the capabilities of catalysts for sustainable applications. The work motivates the development of heterostructures based on transition metal borides by utilizing synergistic effects to facilitate hydrogen production at high current densities.
